Abstract:
The aim of this work was to study Pb accumulation in indoor dust, and health risk of human due to dust exposure. Risk assessment of Pb to human health: Pb is most harmful to human body. The reasons of non-carcinogenic risk in residential area may be that indoor is not swept regularly, in addition, indoor decoration, building materials and other factors may also affect the content of Pb in dust. Non-carcinogenic risk in children is not only more than adults but also beyond the safety threshold. Indoor dust has been a threat to the health of children in Shenyang.Keywords:

Road dust is viewed as one of the major contributors for metal pollution in urban environment and long-term exposure can cause chronic damage through ways of inhalation, ingestion, and dermal contact so they pose a great threat on human health. The article presents a study conducted to determine the concentrations of seven heavy metals in road dust from a chosen street in Cracow, and the impact of heavy metals contamination in surface street dust on human health using Health Risk Assessment. The health risk was assessed using Hazard Quotient (HQ), Health Index (HI) and Carcinogenic Risk (RI).

This article detectes mercury and arsenic concentrations of several kinds of marine products in Bayuquan area in Yingkou.and mades use of Human Health Risk Assessment Model of EPA to assesses the health risk of this area.Results show that human health Risk value of mercury contamination is very low in Bayuquan area in Yingkou,and they are all less than 10-7.There is not any threat to human being,so it is can be neglected A majority of the human health Risk values of arsenic contamination are not in danger,and there are only a few of risk values that to be greater than 10-5,so,in a certain,it proberly endangers the humanbeing,but it must be researched in development.

Spatial distribution analysis of environmental health risk in the Tomsk area was performed. Risk estimation was done according to standard methodology on the basis of geochemical data from the snow cover of the area. The city territory was divided into areas with different levels of ecological damage and human health risk values. The city territory was ranked in accordance to risk level from exposure of trace elements contained in atmospheric dust.

Turkey is one of the biggest cotton producing countries in the world. Defoliant is applied on 17% of the Turkey cotton production, which is similar to average defoliant application in the world. In Turkey, Finish ® and Dropp ® are widely in use as defoliant for desired boll opening in cotton. Finish ® contains ethephon a.i. and cyclanilide a.i., and Dropp ® contains thidiazuron a.i. and diuron a.i. In this study, total risk of defoliant on human health and environment were calculated by POCER (The Pesticide Occupational and Environmental Risk) indicator. The objective of this study was to determine the total risk value of defoliant application in cotton on human health and environment in Turkey. Thidiazuron a.i. has no potential risk on human health and environment. Diuron a.i. has relatively low total risk value on human health. Yet, it has very low risk on environment (0.097). Ethephon a.i. has relatively high total risk on human health (1.550). Cyclanilide a.i. has total risk on human health similar to ethephon a.i. These active ingredients (a.i.) have no potential risk for environment. Consequently, defoliant application in cotton has very low total risk value due to 10 of maximum value.
