Polycyclic aromatic hydrocarbons (PAHs) were analyzed for 136 indoor dust samples collected from Guizhou province, southwest of China. The ∑18PAHs concentrations ranged from 2.18 μg•g-1 to 14.20 μg•g-1 with the mean value of 6.78 μg•g-1. The highest Σ18PAHs concentration was found in dust samples from orefields, followed by city, town and village. Moreover, the mean concentration of Σ18PAHs in ...

Arsenic exposure from burning coal with high arsenic contents occurs in southwest Guizhou, China. Coal in this region contains extremely high concentrations of inorganic arsenic. Arsenic exposure from coal-burning is much higher than exposure from arsenic-contaminated water in other areas of China. The current status and prevention strategies for arsenic poisoning from burning high-arsenic coal...

To investigate the genetic diversity of seven Chinese indigenous meat goat breeds (Tibet goat, Guizhou white goat, Shannan white goat, Yichang white goat, Matou goat, Changjiangsanjiaozhou white goat and Anhui white goat), explain their genetic relationship and assess their integrity and degree of admixture, 302 individuals from these breeds and 42 Boer goats introduced from Africa as reference...

We conducted a survey of 1707 children in 141 impoverished rural areas of Guizhou and Sichuan Provinces in Southwest China. Kato-Katz smear testing of stool samples elucidated the prevalence of ascariasis, trichuriasis and hookworm infections in pre-school and school aged children. Demographic, hygiene, household and anthropometric data were collected to better understand risks for infection in...

Abstract As a province inhabited by ethnic minorities in southwest China, Guizhou is rich tourism and ICH (intangible cultural heritage) resources. The spatial distribution of the utilization resources worth studying, which better for understanding competition situation ICH. This research uses GIS tools analysis, mathematical formulas calculating abundance resources, as well matrix analysis com...

Promoting the coupling coordinated development between ecological protection and high-quality is an important path to achieve sustainable regional around world. Taking Guizhou, China as a typical case, this study builds comprehensive evaluation index system for development, then uses coordination degree model assess spatiotemporal characteristics of development. According findings, Guizhou’s bo...

High-quality development and environmental ecological issues are the core of current economic social in China. While pursuing high-quality development, increasingly severe reality problems cannot be ignored. Under this background, carbon finance is great significance to Based on background new concept, paper constructs a measurement index system with five dimensions 20 secondary indicators, use...

Concentrations of persistent organochlorines (OCs), such as DDTs, hexachlorocyclohexanes (HCHs), hexachlorobenzene (HCB), polychlorinated biphenyls (PCBs), and chlordane compounds (CHLs) were determined in 34 human adipose tissues collected from Guizhou Province, southern China, during 2002. DDT was the predominant contaminant among OCs analyzed; concentrations ranged from 420 to 20 000 ng/g on...
