镉是环境中重要有毒金属元素之一。镉与铅锌伴存,因而铅锌冶炼工业是镉的主要污染源。1968年日本厚生省宣布痛痛病是在妊娠、哺乳、内分泌变化、衰老和营养不足等条件下,由镉的环境污染所致的慢性镉中毒,引起世界各国的关注。马坝地区是广东省有色金属冶炼工业基地,镉对环境污染是当前突出的问题。本研究目的在于掌握该地区镉污染质量及对人群健康的危害,为防治工作和制订卫生标准提供依据。本文分污染现状质量评价和人群健康反应两部分。
Cadmium is one of the most toxic metal elements in the environment. Cadmium and lead and zinc with the existence of lead and zinc smelting industry is the main source of cadmium. In 1968, Japan’s Ministry of Health announced that it is a chronic cadmium poisoning caused by the environmental pollution of cadmium under the conditions of pregnancy, lactation, endocrine change, aging and undernutrition, and has aroused the concern of all countries in the world. Maba area is a non-ferrous metal smelting industrial base in Guangdong Province, cadmium on the environmental pollution is the current outstanding problems. The purpose of this study is to grasp the quality of cadmium pollution in the area and the harm to the health of the population, so as to provide basis for prevention and control work and formulation of health standards. This article is divided into quality assessment of pollution status and population health response in two parts.
