Abstract

The present study aims to estimate geochemical arsenic toxicity in the domestic livestock and possible risk for human and environment caused by them. Daily dietary arsenic intake of an exposed adult cow or bull is nearly 4.56 times higher than control populace and about 3.65 times higher than exposed goats. Arsenic toxicity is well exhibited in all the biomarkers through different statistical interpretations. Arsenic bioconcentration is faster through water compared to paddy straw and mostly manifested in faeces and tail hair in cattle. Cow dung and tail hair are the most pronounced pathways of arsenic biotransformation into environment. A considerable amount of arsenic has been observed in animal proteins such as cow milk, boiled egg yolk, albumen, liver and meat from the exposed livestock. Cow milk arsenic is mostly accumulated in casein (83%) due to the presence of phosphoserine units. SAMOE–risk thermometer, calculated for the most regularly consumed foodstuffs in the area, shows the human health risk in a distinct order: drinking water > rice grain > cow milk > chicken > egg > mutton ranging from class 5 to 1. USEPA health risk assessment model reveals more risk in adults than in children, subsisting severe cancer risk from the foodstuffs where the edible animal proteins cannot be ignored. Therefore, the domestic livestock should be urgently treated with surface water, while provision of both arsenic-free drinking water and nutritional supplements is mandatory for the affected human population to overcome the severe arsenic crisis situation.

在西孟加拉邦砷流行和控制地点生长的牲畜的砷毒性：对人类和环境的风险

摘要

本研究旨在评估家畜的地球化学砷毒性及其对人类和环境可能造成的风险。暴露的成年母牛或公牛的每日膳食砷摄入量比对照人群高近 4.56 倍，比暴露的山羊高约 3.65 倍。通过不同的统计解释，砷毒性在所有生物标志物中都得到了很好的展示。与稻草相比，砷在水中的生物富集速度更快，主要表现在牛的粪便和尾毛中。牛粪和尾毛是砷生物转化到环境中最明显的途径。已在动物蛋白质中观察到大量砷，例如牛奶、煮沸的蛋黄、蛋白、肝脏和暴露的牲畜的肉。由于磷酸丝氨酸单位的存在，牛奶中的砷主要在酪蛋白中积累 (83%)。SAMOE 风险温度计针对该地区最常食用的食品进行计算，按不同的顺序显示人类健康风险：饮用水 > 米粒 > 牛奶 > 鸡肉 > 鸡蛋 > 羊肉，范围从 5 级到 1 级。 USEPA 健康风险评估模型揭示了成人的风险高于儿童，存在来自食品的严重癌症风险，而食用动物蛋白是不容忽视的。因此，家畜应紧急用地表水处理，同时为受影响人群提供无砷饮用水和营养补充剂，以克服严重的砷危机局面。计算该地区最常食用的食品，按不同的顺序显示人类健康风险：饮用水 > 米粒 > 牛奶 > 鸡肉 > 鸡蛋 > 羊肉，范围从 5 级到 1 级。 USEPA 健康风险评估模型揭示了更多风险与儿童相比，成人比儿童存在严重的癌症风险，而食品中的可食用动物蛋白不容忽视。因此，家畜应紧急用地表水处理，同时为受影响人群提供无砷饮用水和营养补充剂，以克服严重的砷危机局面。计算该地区最常食用的食品，按不同的顺序显示人类健康风险：饮用水 > 米粒 > 牛奶 > 鸡肉 > 鸡蛋 > 羊肉，范围从 5 级到 1 级。 USEPA 健康风险评估模型揭示了更多风险与儿童相比，成人比儿童存在严重的癌症风险，而食品中的可食用动物蛋白不容忽视。因此，家畜应紧急用地表水处理，同时为受影响人群提供无砷饮用水和营养补充剂，以克服严重的砷危机局面。羊肉的等级从 5 级到 1 级不等。美国环保署健康风险评估模型显示，成人的风险高于儿童，食用动物蛋白不可忽视的食品存在严重的癌症风险。因此，家畜应紧急用地表水处理，同时为受影响人群提供无砷饮用水和营养补充剂，以克服严重的砷危机局面。羊肉的等级从 5 级到 1 级不等。美国环保署健康风险评估模型显示，成人的风险高于儿童，食用动物蛋白不可忽视的食品存在严重的癌症风险。因此，家畜应紧急用地表水处理，同时为受影响人群提供无砷饮用水和营养补充剂，以克服严重的砷危机局面。
