A first evaluation on the use of Ardea albus feathers as bioindicators of mercury burden in Amazonian ecosystems Acta Amazonica
Gomes,Andreza Lourdes; Vieira,José Luiz Fernandes; Pinheiro,Maria da Conceição Nascimento; Marceliano,Maria Luiza Videira.
We evaluated in this study the total mercury concentration in feathers of Ardea albus collected in a colony located in the city of Belem-PA, Brazil in a prospective trial for its use as bioindicators of mercury burden in Amazonia ecosystems. An Atomic absorption spectrophotometry with gold amalgamation was used for the metal determination. The total mercury average concentration in body feathers was 2.2 ± 1.5 µg.g-1 and 1.3 ± 0.9 µg.g-1 in wing feathers. No correlation was observed between total mercury concentration and the length of body or wing feathers. Total mercury concentration was above 5 µg.g-1 dry weight in only one body feather sample.

A RENEWAL THEORETIC APPROACH TO ENVIRONMENTAL STANDARD SETTING AgEcon
Batabyal, Amitrajeet A..
The process of environmental regulation is usually a two-step one. In the first step, a standard for environmental quality is set. Then, in the second step, a regulatory mechanism is put in place to achieve the standard. In this paper I show how renewal theory can be used to set the quality standard optimally.

AN AGENDA FOR THE DESIGN AND STUDY OF INTERNATIONAL ENVIRONMENTAL AGREEMENTS AgEcon
Batabyal, Amitrajeet A..
The combination of a general greening of international political debate, and the events of 1992 at the Rio Earth summit have led to great interest in the question of global environmental protection. While it is recognized that international environmental agreements (IEAs) are the means by which the earth’s fragile environment is most likely to be protected, this recognition has been recent. Hence, there is very little formal research on the design and study of IEAs. As such, in this paper, I propose and describe a research agenda for the design and study of IEAs. Very generally, I propose that we frame the IEA design question as a problem in mechanism design. We will then be able to use, inter alia, the theory of common agency and the theory of hierarchies...

AVALIAÇÃO DO PROCESSO DE IMPLANTAÇÃO DE PROJETOS DEMONSTRATIVOS PARA A RECUPERAÇÃO DE MATAS CILIARES NO ESTADO DE SÃO PAULO AgEcon
Chabaribery, Denyse; Monteiro, Ana Victoria; Silva, Jose Roberto; Ramos, Soraia Fatima.
O artigo faz a avaliação da fase inicial de implantação de projetos demonstrativos para recuperação com espécies nativas de áreas degradadas em mata ciliar em três microbacias no Estado de São Paulo. O arcabouço teórico considerou o projeto como um modelo de conservação da biodiversidade, entendendo que deveria ter havido um enfoque transdisciplinar das instituições parceiras. A pesquisa utilizou-se das técnicas de delphi para levantar os depoimentos dos envolvidos no acompanhamento e na execução das áreas experimentais. Em parte a transdisciplinaridade foi conseguida e houve sucesso no plantio das áreas pilotos em três microbacias estudadas. Mas, a avaliação geral foi de que as equipes locais não tiveram o apoio necessário dos componentes de educação...

Avaliação dos problemas enfrentados no manejo do caramujo gigante africano Achatina fulica (Gastropoda: Pulmonata) no Brasil Rev. Bras. Zool.
Colley,Eduardo; Fischer,Marta Luciane.
The giant African snail Achatina fulica Bowdich, 1822 was introduced into Paraná, Brazil, in the 1980s. Since then, it has spread across the country, despite its known invasive status on a global scale. The main objective of this study was to assess the problems faced in the management of the giant African snail. To accomplish that, we gathered and analyzed information available on the internet, scientific databases, field studies, as well as interviews and consultations with official agencies, NGOs, museums, the scientific community and people that coexist with the species. Despite the fact that extensive information has been generated regarding A. fulica (1,340 articles, 65 summaries in national annals, 40,700 pages on the internet), essential to promote...

Az élelmiszer-ipari vállalkozások környezeti teljesítménye és a pénzügyi eredmények AgEcon
Deak, Zsuzsanna; Hajdu, Istvanne.
Kutatásunk célja fényt deríteni arra, hogy a vállalkozások környezeti teljesítménye befolyásolja-e pénzügyi teljesítményüket, továbbá az, hogy milyen szerepet játszik ebben a média, hogyan változott az elmúlt időszakban a vállalkozások zöld erőfeszítéseinek megítélése? Megállapítható, hogy azokban a vállalkozásokban, amelyekben a média és a befektetők környezeti teljesítményüket kedvezően ítélik meg, magasabbak a megtérülési (ROE) mutatók, mint azokban, amelyeknek környezeti teljesítményét nem ítélik meg pozitívan. A magyarországi társadalomban a nem anyagi értékek iránti érzékenység és a környezettudatosság alacsony szintű. A társadalmi értékrendben alárendelt szerepet játszó környezetvédelmi gondolkozásra – reklámérték híján – a média mérsékelten hat. Ez...

CONSISTENCY AND OPTIMALITY IN A DYNAMIC GAME OF POLLUTION CONTROL I: COMPETITION AgEcon
Batabyal, Amitrajeet A..
I model the interaction between a regulator and polluting firms as a Stackelberg differential game in which the regulator leads. The firms create pollution, which results in a stock externality. I analyze the intertemporal effects of alternate pollution control measures in a competitive industry. The principal issue here concerns the dynamic inconsistency of the optimal solution. Inter alia, I compare the steady state levels of pollution under optimal and under time consistent policies. Forthcoming in Environmental and Resource Economics

DEVELOPING COUNTRIES AND ENVIRONMENTAL PROTECTION: THE EFFECT OF BUDGET BALANCE AND POLLUTION CEILING CONSTRAINTS AgEcon
Batabyal, Amitrajeet A..
I analyze the problem faced by an asymmetrically informed supranational governmental authority (SNGA) with limited financial resources who wishes to design an International Environmental Agreement (IEA). The SNGA cannot contract directly with polluting firms in the various LDCs, but he must deal with such firms through their governments. I study this tripartite hierarchical interaction and focus on the properties of the optimal ex post contracts (IEAs), which can be implemented by the SNGA, in turn, in the case where governments and firms in each nation do not collude and then in the case where governments and firms do collude. I find that the monetary transfers necessary to induce optimal behavior by governments and firms are not very sensitive to the...

Developing realistic exposure scenarios for environmental risk assessment of pesticides in brazilian surface water Repositório Alice
MINGOTI, R.; SPADOTTO, C. A.; BERALDO, G. N.; VALLE, L. B.; BRASCO, M. A.; FARIAS, A. R.; LOVISI FILHO, E..
Standard scenarios increase the consistency of the regulatory evaluation process by minimizing the subjective influence when performing the pesticide environmental concentration - PEC calculation, also make interpretation much easier and enable the adoption of a consistem scientific process for a Tier 1 evaluation (FOCUS, 2000). The brazilian lnstitute of the Environment and Renewable Natural Resources (IBAMA) adopts the United States Environmental Protection Agency (USEPA) methodology (IBAMA. 2016), using the "standard farm pond" scenario (Parker et al., 1995) for surface water in the Tier 1 evaluation and, therefore, it may lead to the registration of pesticides without considering brazilian agricultural scenarios in environmental risk assessment - ERA.

Environmental economics and valuation: towards a practical investment framework for Catchment Management Authorities in New South Wales AgEcon
Farquharson, Robert J.; Hill, Christine M.; Bennett, Jeffrey W.; Tracey, Jacqueline.
The Catchment Management Authorities in New South Wales have programs that are collectively investing $436 million over four years to achieve catchment-wide natural resource/environmental improvements. In this paper, we consider the question of how to best allocate these resources so as to increase the well-being of the public within catchments and the state. We consider the current approaches used by CMAs and make a case for Benefit-Cost Analysis as an alternative means of assessing ex ante questions of priority setting at the catchment level and for project appraisal. A major issue for BCA is the estimation of potential benefits from project investments, particularly the estimation of values that catchment communities and those living outside the...

Frequency of microorganisms isolated at different stages of lactation and milk production loss associated with somatic cell count and to mastitis-causing pathogens Arq. Bras. Med. Vet. Zootec.
Costa,H.N.; Lage,C.F.A.; Malacco,V.M.R.; Belli,A.L.; Carvalho,A.U.; Facury,E.J.; Molina,L.R..
ABSTRACT The aim of this study was to evaluate the frequency of isolation of agents causing subclinical mastitis in a herd and to estimate production losses associated with SCC> 200,000cells/mL. Three 7-day interval microbiological cultures were performed in all lactating animals from the same farm that was evaluated from June to July. To evaluate the negative and positive isolation frequencies between the lactation phases, a Chi-square test was performed. Simple linear regressions were performed to evaluate the lactation curve of animals grouped by pathogens isolated from negative cows in the microbiological culture and with SCC <200,000cells/mL. To estimate the production losses between the groups, regression coefficients were used. Results found...

GAME MODELS OF ENVIRONMENTAL POLICY IN AN OPEN ECONOMY AgEcon
Batabyal, Amitrajeet A..
In this paper we study some aspects of the question of international environmental regulation from a game theoretic perspective. We address two broad questions. First, we examine the circumstances under which the pursuit of unilateral environmental policy by a country in a Stackelberg game will make that country worse off. Second, we study the effects of environmental regulation by means of alternate price control instruments in a Stackelberg game where there is transboundary pollution. We find that there are plausible theoretical circumstances in which the pursuit of unilateral environmental policy is not a good idea. Further, we show that in choosing between alternate pollution control instruments, national governments typically face a tradeoff between...

Holstein white coat color and performance: phenotypic, genetic and environmental correlations Braz. J. Genet.
Becerril,Carlos M.; Wilcox,Charles J.; Guerrero,Victor M..
Correlations of measures of percentages of white coat color, five measures of production and two measures of reproduction were obtained from 4293 first lactation Holsteins from eight Florida dairy farms. Percentages of white coat color were analyzed as recorded and transformed by an extension of Box-Cox procedures. Statistical analyses were by derivative-free restricted maximum likelihood (DFREML) with an animal model. Phenotypic and genetic correlations of white percentage (not transformed) were with milk yield, 0.047 and 0.097; fat yield, 0.002 and 0.004; fat percentage, -0.047 and -0.090; protein yield, 0.024 and 0.048; protein percentage, -0.070 and -0.116; days open, -0.012 and -0.065; and calving interval, -0.007 and -0.029. Changes in magnitude of...

In vitro antifungal susceptibility of clinical and environmental isolates of Aspergillus fumigatus and Aspergillus flavus in Brazil BJID
Denardi,Laura Bedin; Hoch Dalla-Lana,Bianca; Pantella Kunz de Jesus,Francielli; Bittencourt Severo,Cecília; Santurio,Janio Morais; Zanette,Régis Adriel; Alves,Sydney Hartz.
ABSTRACT The in vitro susceptibility of 105 clinical and environmental strains of Aspergillus fumigatus and Aspergillus flavus to antifungal drugs, such as amphotericin B, azoles, and echinocandins was evaluated by the broth microdilution method proposed by the European Committee on Antimicrobial Susceptibility Testing (EUCAST). Following the EUCAST-proposed breakpoints, 20% and 25% of the clinical and environmental isolates of A. fumigatus, respectively, were found to be resistant to itraconazole (Minimal Inhibitory Concentration, MIC > 2.0 mg/L). Voriconazole showed good activity against A. fumigatus and A. flavus strains, except for one clinical strain of A. fumigatus whose MIC was 4.0 mg/L. Posaconazole (≤0.25 mg/L) also showed appreciable activity...
