Abstract Given the amplified concern surrounding PFAS, states are proactively filing lawsuits on behalf of their citizens and enacting legislation to combat this nation-wide contamination epidemic. However, given the 2016 Amendment to the Toxic Substances Control Act, states looking to regulate the manufacturing or looking to ratify a state-wide ban on the manufacturing of such chemicals may face preemption under actions taken by the U.S. EPA. This article focuses on the possible loss of state autonomy with regards to PFAS regulation and addresses issues states might face given the restrictive nature of the newly enacted preemption provisions of TSCA.
摘要鉴于对PFAS的担忧加剧,各州正在积极代表其公民提起诉讼,并制定立法来对抗这一全国性的污染流行病。然而,鉴于2016年《有毒物质控制法修正案》,根据美国环保局采取的行动,希望监管此类化学品的生产或批准全州范围内禁止此类化学品生产的州可能会面临优先权。本文重点关注PFAS监管方面可能失去的国家自主权,并解决了鉴于新颁布的TSCA优先购买权条款的限制性质,各州可能面临的问题。

Abstract As the largest source of carbon-free energy in the United States, nuclear energy must play a vital role in reducing emissions. This article suggests the Green New Deal, an ambitious federal proposal to address climate change, should aim to preserve the existing nuclear fleet by authorizing states to establish zero emission credit (“ZEC”) programs. The ZEC programs will provide credits, in the form of revenue, for the carbon-free attribute of nuclear energy. This article posits the ZEC programs should be based on a model ZEC program developed by the Federal Energy Regulatory Commission and explicitly authorized by amendment of the Federal Power Act to avoid issues of preemption.
摘要核能作为美国最大的无碳能源,必须在减少排放方面发挥至关重要的作用。这篇文章建议,绿色新政是一项应对气候变化的雄心勃勃的联邦提案,其目的应该是通过授权各州建立零排放信贷(“ZEC”)计划来保护现有的核舰队。ZEC计划将以收入的形式为核能的无碳属性提供信贷。本文认为,ZEC计划应基于联邦能源监管委员会制定的ZEC计划范本,并经《联邦电力法》修正案明确授权,以避免优先购买权问题。

Legacy Contaminants of Emerging Concern: Lead (Pb), Flint (MI), and Human Health 新关注的遗留污染物:铅(Pb),燧石(MI),和人类健康

Abstract As a heavy metal industrially mined for millenia, lead (Pb) is a legacy contaminant. It is also a contaminant of emerging concern because of its persistence, toxicity, and recent discovery of its resurgence in drinking water serving homes and schools, recently and most notoriously in Flint, Michigan. Concern about lead, however, has reemerged beyond Flint, exemplifying adoption of bad science policy despite availability of relevant good science. Much is known about lead toxicity, and profiled here. Whereas adults chronically exposed to lead may experience peripheral neuropathy, infants and children are more susceptible. They constitute sensitive subpopulations because their blood-brain barriers are immature, making them susceptible to central nervous system effects, most notably reduced IQ, when lead penetrates to developing brains. Failure to protect disadvantaged populations in Flint and beyond despite availability of proven science and inexpensive technology also exemplifies instances of environmental injustice. Emerging concern about lead thus illustrates failure of social as well as science policy. A critical lesson to be learned is that vigilance must be maintained, as knowledge about lead exposure and toxic effects provided by science does not automatically result in consistent and evenhanded legal and regulatory protection provided by government.
摘要铅作为一种具有上千年工业开采历史的重金属,是一种遗留污染物。由于它的持久性和毒性,以及最近在家庭和学校的饮用水中发现它的死灰复燃,这也是一种日益受到关注的污染物,最近最臭名昭著的是在密歇根州的弗林特。然而,对铅的担忧在弗林特以外的地方重新出现,这是尽管有相关的可靠科学,但仍采用不良科学政策的例证。我们对铅的毒性了解很多,在此进行介绍。而长期接触铅的成年人可能会经历周围神经病变,婴儿和儿童更容易受到影响。他们属于敏感亚群,因为他们的血脑屏障还不成熟,容易受到中枢神经系统的影响,当铅渗入发育中的大脑时,最明显的是智商下降。尽管有可靠的科学和廉价的技术,但未能保护弗林特及其他地区的弱势群体,这也是环境不公正的例证。因此,对铅的日益关注说明了社会政策和科学政策的失败。需要吸取的一个重要教训是,必须保持警惕,因为科学提供的关于铅接触和毒性影响的知识不会自动导致政府提供一致和公平的法律和监管保护。

Abstract Color removal from wastewater has been a matter of concern, both in the esthetic sense and health point of view. Color removal from textile effluents on a continuous industrial scale has been given much attention in the last few years, not only because of its potential toxicity, but also due to its visibility problem. The ability of wheat husk to act as biosorption medium in the removal of dyes from aqueous solution was successfylly investigated. The analysis of dye remaining in the solution was done colourimetrically using a spectrophotometer. It may be concluded that easy availability and suitability for production of bioadsorbent from wheat husk makes it one of the materials that can be used for removal of RB 19 and RB 195 from waste water.
摘要从审美和健康的角度来看,从废水中去除颜色一直是一个令人关注的问题。在过去的几年里,连续工业规模的纺织品废水的颜色去除受到了广泛的关注,不仅因为其潜在的毒性,还因为其可见性问题。成功地研究了小麦壳作为生物吸附介质去除水溶液中染料的能力。使用分光光度计对溶液中残留的染料进行色度分析。可以得出结论,从麦壳中生产生物吸附剂的容易获得性和适用性使其成为可用于从废水中去除RB19和RB195的材料之一。

Too many companies face significant financial exposure by not having the right insurance in place when there is an environmental claim. General liability insurance policies and property policies exclude most fact patterns involving alleged or actual environmental or pollution damages. The decision to leave a gap in insurance and self-insure environmental exposures should be a thoughtful one, particularly when there are more emerging cancer-causing chemicals being studied and regulated, and a greater variety of detection equipment are being utilized. My 2019 Environmental Claims Journal Editor’s Note addressed emerging contaminants 1,4 Dioxane, and Perfluoroalkyl substances (PFA’s) now the topic of a current movie Dark Waters, resulting in much more expensive remedial investigations and cleanups. The New York State Department of Environmental Conservation (NYSDEC) announced in 2019 they are requiring testing for this new class of chemicals for projects under NYSDEC’s supervision. In the past two years, New York State has set aside over $500 million to upgrade water treatment systems to include an Advanced Oxidation Process because these contaminants are, unfortunately, already in our drinking water. On December 9, 2019, Governor Cuomo approved legislation eliminating the sale of products containing 1,4-dioxane in New York State. Prior studies by the USEPA estimated more than 25,000 prior dry cleaners had used perc/PCE which contaminated the dry cleaner’s site and neighboring properties. One tablespoon of PCE is enough to contaminate two Olympic-sized swimming pools. Pending toxic tort litigation often involves vapor intrusion from solvents such as PCE to the neighboring residences, schools and other buildings which are located above the soil and groundwater plumes. The spillage of solvents was common from storage leaks, transfers, equipment failures, septic systems and sewers, and improper waste disposal in backyards and dumpsters. While PCE testing and remediation is ongoing, numerous other contaminants are regularly detected in the process creating liability disputes among property owners. For many large and small clients’ environmental liabilities have caused severe financial losses and some public relations disasters. In the past couple of years, we continue to experience claims frequency for asbestos exposures, fuel spills, mold contamination claims, lead ingestion and lead dust, carbon monoxide, legionella, sick building indoor air quality, vapor intrusion, chemical releases, silica and dust, PCBs, leaking sewer lines, midnight dumping of hazardous materials, and often offsite disposal based on waste manifests. In addition, a concern exists by many insureds, more than ever, regarding the intentional release of a bioterrorism agent, which can be a virus or bacteria, as there are more than 45 bioterrorism agents identified by the U.S. Center for Disease Control.

当有环境索赔时,太多的公司由于没有适当的保险而面临重大的财务风险。一般责任保险单和财产保险单不包括大多数涉及指称的或实际的环境或污染损害的事实模式。在保险和自我投保环境风险方面留下空白的决定应该是一个深思熟虑的决定,特别是当越来越多的新出现的致癌化学物质正在被研究和监管,越来越多的检测设备正在被使用。我的2019年《环境索赔杂志》编者按讨论了新出现的污染物1,4二恶烷和全氟烷基物质(PFA),现在是当前电影《黑暗水域》的主题,导致更昂贵的补救调查和清理。纽约州环境保护部(NYSDEC)于2019年宣布,他们要求对NYSDEC监督下的项目进行这类新化学品的测试。在过去的两年里,纽约州已经拨出5亿多美元用于升级水处理系统,包括高级氧化过程,因为不幸的是,这些污染物已经存在于我们的饮用水中。2019年12月9日,Cuomo州长批准了一项立法,禁止在纽约州销售含有1,4-二恶烷的产品。美国环保署先前的研究估计,超过25,000家干洗店使用过全氯乙烯,污染了干洗店的场地和邻近的物业。一汤匙的PCE足以污染两个奥运会规格的游泳池。悬而未决的有毒侵权诉讼通常涉及溶剂(如PCE)对邻近住宅、学校和其他建筑物的蒸汽侵入,这些建筑物位于土壤和地下水羽流之上。溶剂的泄漏很常见,包括储存泄漏、转移、设备故障、化粪池系统和下水道,以及后院和垃圾箱中的不当废物处理。虽然PCE测试和补救正在进行中,但在此过程中经常检测到许多其他污染物,从而导致业主之间的责任纠纷。对于许多大大小小的客户来说,环境责任已经造成了严重的经济损失和一些公关灾难。在过去的几年里,我们继续经历石棉暴露,燃料泄漏,霉菌污染索赔,铅摄入和铅尘,一氧化碳,军团菌,室内空气质量,蒸汽侵入,化学物质释放,二氧化硅和粉尘,多氯联苯,下水道泄漏,午夜倾倒有害物质,以及经常根据废物清单进行非现场处理的索赔频率。此外,许多被保险人比以往任何时候都更加担心故意释放生物恐怖主义制剂,这种制剂可以是病毒或细菌,因为美国疾病控制中心确定的生物恐怖主义制剂超过45种。环境保险市场已经发展到弥补这一差距,并为不同部门提供专门的环境政策形式,包括医疗保健、酒店、大学和娱乐场所、石油和天然气、承包商、混合房地产投资组合,甚至为制造和分销企业。

Abstract The article suggests a new view on the issues of protection of environmental human rights in environmentally unfavorable areas. A diversity of approaches in Russia and republics of the former USSR granted a special legal status to areas which caused environmental harm due to natural disasters and manmade disasters, In addition, ineffective environmental policies allowed hazardous industries to pollute the environment for many years. New environmental legal solutions must be developed and implemented in developing countries with the active assistance of the international community to ensure environmental human rights on a global rather than national scale. The new proposed legal requirements should focus on the most environmentally impaired areas based on utilizing specific classifications and criteria.
文章对环境不利地区的环境人权保护问题提出了新的看法。俄罗斯和前苏联各共和国的各种做法赋予了因自然灾害和人为灾害造成环境损害的地区特殊的法律地位。此外,无效的环境政策使危险行业多年来污染环境。必须在国际社会的积极协助下,在发展中国家制定和实施新的环境法律解决方案,以确保全球而非国家范围内的环境人权。新的拟议法律要求应在利用具体分类和标准的基础上,侧重于环境受损最严重的地区。

Abstract Benzene, toluene, ethylbenzene, and xylene (BTEX) compounds are known for their toxic effects. The ambient BTEX levels were studied at various urban vegetative locations of Delhi to assess the health risks involved. The average concentrations were higher for toluene and xylene among BTEX compounds. The cancer risks for benzene exceeded the benchmark limits of USEPA and WHO. The study suggests that the vegetative areas in Delhi are not safe for public health and regulatory bodies need to initiate some action.
摘要苯、甲苯、乙苯和二甲苯(BTEX)化合物因其毒性作用而闻名。对德里不同城市植被区的环境BTEX水平进行了研究,以评估所涉及的健康风险。在BTEX化合物中,甲苯和二甲苯的平均浓度较高。苯的癌症风险超过了美国环境保护局和世界卫生组织的基准限值。这项研究表明,德里的植被区对公共卫生来说并不安全,监管机构需要采取一些行动。

Renewal Acute Toxicity of Broad-Spectrum Herbicide, Paraquat Dichloride in Channa punctatus (Bloch) 广谱除草剂二氯百草枯对斑沟的急性毒性更新
Q3 Environmental Science Pub Date : 2019-06-27 DOI: 10.1080/10406026.2019.1609796

Abstract Paraquat dichloride (PD) is a major contaminant in aquatic environment and is a cause of concern to different organisms, especially to fishes, as it causes different changes in behavioral and morphological to aquatic creatures. Hence, the objectives of the study are to examine the acute toxicity, behavioral and morphological alterations in air-breathing teleost fish, Channa punctatus (CP) (Bloch). Renewal acute toxicity was performed to calculate the lethal concentration (LC50) by Finney’s probit analysis to CP by exposure to wide range of PD concentrations (30, 60, 90, 120, 150 mg/L) for 24, 48, 72 and 96 h. The LC50 values determined are 93.36, 82.22, 67.93 and 65.87 mg/L for 24, 48, 72 and 96 h, respectively. Maximum allowable toxicant concentrations (MATC) defined by LC50 value is found to be 0.6587 mg/L. The upper and lower 95 percent confidence limit (Fiducial limit) are in narrow range for 24, 48, 72 and 96 h, respectively, and thus results of the experiments are considered good. Fiducial limit calculated helps us to state that the LC50 falls within the specified limit and helps in constructing of toxicity curve. LC50 value gradually decreases with increase in time. Mortality rate was dose-time dependent and increased with increase in concentration. The behavioral changes provide biologically relevant endpoints in evaluating toxicity testing. Deviation from baseline behavior was noticed. Morphological deformities were also seen. The present study provides a clear indication of the toxicity of PD, and is highly toxic even at low level. Hence, it is recommended that appropriate eco-toxicological risk assessment should be made and indiscriminate use of PD by farmers should be discouraged particularly in areas close to aquatic environment.
摘要二氯百草枯(PD)是水生环境中的一种主要污染物,它会导致水生生物在行为和形态上发生不同的变化,引起不同生物特别是鱼类的关注。因此,本研究的目的是检测呼吸空气的硬骨鱼斑钱鱼(CP)(Bloch)的急性毒性、行为和形态变化。通过Finney的probit分析,通过暴露于各种PD浓度(30、60、90、120、150 mg/L)用于24、48、72和96 h.测定的LC50值分别为93.36、82.22、67.93和65.87 24、48、72和96的mg/L h、 分别。由LC50值定义的最大允许毒物浓度(MATC)为0.6587 mg/L。95%置信度上限和下限(基准限)在24、48、72和96的窄范围内 h、 因此实验结果被认为是良好的。计算出的基准限值有助于说明LC50在规定的限值范围内,并有助于构建毒性曲线。LC50值随着时间的增加而逐渐降低。死亡率是剂量-时间依赖性的,并且随着浓度的增加而增加。行为变化提供了评估毒性测试的生物学相关终点。注意到偏离基线行为。还发现了形态畸形。本研究提供了PD毒性的明确指示,即使在低水平下也具有高毒性。因此,建议进行适当的生态毒理学风险评估,并劝阻农民滥用PD,特别是在靠近水生环境的地区。

Hence, the objectives of the study are to examine the acute toxicity, behavioral and morphological alterations in air-breathing teleost fish, Channa punctatus (CP) (Bloch). Renewal acute toxicity was performed to calculate the lethal concentration (LC50) by Finney’s probit analysis to CP by exposure to wide range of PD concentrations (30, 60, 90, 120, 150 mg/L) for 24, 48, 72 and 96 h. The LC50 values determined are 93.36, 82.22, 67.93 and 65.87 mg/L for 24, 48, 72 and 96 h, respectively. Maximum allowable toxicant concentrations (MATC) defined by LC50 value is found to be 0.6587 mg/L. The upper and lower 95 percent confidence limit (Fiducial limit) are in narrow range for 24, 48, 72 and 96 h, respectively, and thus results of the experiments are considered good. Fiducial limit calculated helps us to state that the LC50 falls within the specified limit and helps in constructing of toxicity curve. LC50 value gradually decreases with increase in time. Mortality rate was dose-time dependent and increased with increase in concentration. The behavioral changes provide biologically relevant endpoints in evaluating toxicity testing. Deviation from baseline behavior was noticed. Morphological deformities were also seen. The present study provides a clear indication of the toxicity of PD, and is highly toxic even at low level.

Abstract To fight atmospheric air pollution, the Georgian government has implemented a law about vehicle inspection. The aim of this survey is to determine under which conditions are owners of technically faulty vehicles ready to give up using technically faulty cars. Within the qualitative study the in-depth interviews were conducted. Taxi drivers think that this law is harmful to them though they appreciate the efficacy of vehicle inspections. Controls should be placed on the quality of fuel as part of the development of public transport while increasing awareness about the harmful effects of atmospheric air pollution.
为了对抗大气污染,格鲁吉亚政府实施了一项关于车辆检查的法律。这项调查的目的是确定在何种情况下,技术上有缺陷的车辆的车主准备放弃使用技术上有缺陷的汽车。在定性研究中进行了深度访谈。出租车司机认为这项法律对他们有害,尽管他们欣赏车辆检查的功效。作为公共交通发展的一部分,应该控制燃料的质量,同时提高人们对大气污染有害影响的认识。

Abstract The severity of environmental insurance claims related to large multi-PRP Superfund sites has grown over the last 30 years. When an insured files a Superfund-related claim, allocated costs to the insured are typically unknown. Assessing the insured’s likely share of future cleanup costs is challenging. This article proposes a simple approach that allows claims professionals to visualize where their insured stands relative to other PRPs' potential allocation of cleanup costs. The resulting color-coded “heat map” allows claims professionals to easily assess and prioritize potential insured losses. It also provides a starting point for settlement negotiations, thus reducing frictional costs.
在过去的30年里,与大型多prp超级基金站点相关的环境保险索赔的严重性有所增长。当被保险人提出与超级基金相关的索赔时,分配给被保险人的费用通常是未知的。评估被保险人在未来清理成本中可能承担的份额是一项挑战。本文提出了一种简单的方法,允许理赔专业人员可视化他们的被保险人相对于其他prp的潜在清理成本分配的位置。由此产生的彩色编码“热图”允许理赔专业人员轻松评估和优先考虑潜在的保险损失。它还为解决谈判提供了一个起点,从而减少了摩擦成本。
