Vulnerability of small-scale fishers to benzene exposure and the current knowledge gap on benzene-exposure in Brazilian fishers

Benzene Reference Exposure Levels

Matching Fishers’ Knowledge and Landing Data to Overcome Data Missing in Small-Scale Fisheries

BACKGROUND In small-scale fishery, information provided by fishers has been useful to complement current and past lack of knowledge on species and environment. METHODOLOGY Through interviews, 82 fishers from the largest fishing communities on the north and south borders of a Brazilian northeastern coastal state provided estimates of the catch per unit effort (CPUE) and rank of species abundan...

The effect of respiratory exposure to benzene, toluene, xylene and ethyl benzene on the spirometric indices among the petroleum products loading workers

Abstract Background and Aim: Benzene, toluene, xylene and ethyl benzene (BTEX) are the most important aromatic compounds in petroleum products. BTEX compounds due to their high vapor pressure, easily change to gas form and mixed with ambient air. Petroleum products loading workers are exposed to these compounds by the inhalation of BTEX compounds. The aim of this study was to evaluate the ef...

Occupational exposure to benzene in China.

Of a total of 528,729 workers exposed to benzene or benzene mixtures in China, 508,818 (96.23%) were examined. Altogether 2,676 cases of benzene poisoning were found, a prevalence of 0.15%. A higher prevalence of benzene poisoning was found in the cities of Hangjou, Hefei, Nanjing, Shenyang, and Xian. The geometric mean concentration of benzene in 50,255 workplaces was 18.1 mg/m3 but 64.6% of t...
