Effects of 1-bromopropane on liver and kidney functions of exposed workers / 中华劳动卫生职业病杂志

<p><b>OBJECTIVE</b>To study the effects of 1-bromopropane (1-BP) on liver and kidney functions of exposed workers.</p><p><b>METHODS</b>Occupational health situation in three 1-BP plants was investigated. Fifty-four workers from the 1-BP manufacturing line were chose to be contact group, while 42 workers from non-1-BP manufacturing line as control group. All workers underwent questionnaire survey, liver function test as well as kidney function test.</p><p><b>RESULT</b>Working years has no impact on liver and kidney functions of workers from contact group. Compared with the control, liver and kidney functions test of the two groups showed no statistical difference either.</p><p><b>CONCLUSION</b>The present investigation doesn't prove any impact of occupational 1-BP exposure on worker's liver and kidney functions.</p>

Contamination of persistent organic pollutants (POPs) and relevant management in China.

The status of typical persistent organic pollutant (POP) contamination in many media (e.g., farm produce, soil, human milk, water, and sediments) was surveyed and China's relevant countermeasures for controlling POPs were analyzed in this paper. The results showed that the proportion of organochlorine pesticides (OCPs) to all kinds of pesticides has descended significantly since 1983 when the OCPs were forbidden from being used. The spatial distribution characteristic of pesticide application in the whole country was as follows: southeast>central>northwest. The pesticide residues in food with high fat and high protein content were more than that in foodstuffs. The residual concentration in soil in the whole country was as follows: south>central>north. Furthermore, in vegetable fields, the residual concentration was higher than that in crop fields. As for human milk, the retained amount tended to decrease. In the recent two decades, although the reduction was 81.5%, it was still higher than that in some developed European and American countries. The rank of the residual concentrations of OCPs in different media was: human milk>animal foodstuff>soil>vegetable food>water and sediment. The initial relevant POP management in China can be traced back to 1982 when the Ordinance of Pesticide Management was enacted. Now, environmental control of POPs in China is close to the international level. The legal management system of POPs can be divided into four facets, including 3 regulations, 6 ordinances, and 20 standards. However, on the whole, most of the existing regulations do not refer to POPs directly. Only some clauses mention POPs and lack pertinent, explicit statements on POP pollution and control. Legislation is urgently needed for more effective environmental management to enhance POP control.
