This study assessed air pollution levels for respirable particulate matter (PM2.5 and PM10) and heavy metals (lead, chromium, nickel, cadmium, zinc and copper) adjacent to a cement factory in Ewekoro and neighbouring communities (Papalantoro, Lapeleko and Itori) in Ogun State, Nigeria. Respirable particulate matter (PM2.5 and PM10) and heavy metals were measured using an ARA N-FRM cassette sampler. Each location sampled was monitored for eight continuous hours daily for 12 days. The PM2.5, PM10 and heavy metals results were compared with different standards, including those of the World Health Organization (WHO), Nigeria’s National Environmental Standard and Regulation Enforcement Agency (NESREA) and Canadian Ambient Air Quality Standards (CAAQS). The PM levels fell within 11 - 19 μg/m3 of the air management level of CAAQS, which signifies continuous actions are needed to improve air quality in the areas monitored but below the NESREA standard. The mean Cd, Cr and Ni concentrations in the cement factory area and the impacted neighbourhoods are higher than the WHO/EU permissible limits, while Zn and Cu were below the WHO/EU permissible limit. A risk assessment hazard quotient (HQ) for Cr was above the WHO/EU safe level (=1) in adults and children throµgh ingestion, inhalation and dermal contact at all the monitoring sites. The HQ for Ni and Cd was higher than the safe level in the cement factory area and Papalantoro, while Zn was at safe levels.展开更多

Principles and theories of the renovation design were introduced, it was proposed that protection and landscape renovation of industrial heritage had to be insisted to make regular and unique overall spatial layouts. On this basis, design approaches for the wasteland landscape renovation of the steel-casting factory were proposed as "maintaining original images, realizing the functional substitution; optimizing spatial structure; updating seriously-damaged industrial facilities with insignificant functionality; improving and recovering landscape soil; recovering and reconstructing vegetation".展开更多

[Method] The twin-embryos seed of autotetraploid rice DER10-04-01 was taken as the receptor material,and the Elymus dahuricus Turcz. was used as materials to provide DNA to carry out the ion beam mediated experiment. And the fractional factorial design method was used to study the parameters of low enery N＋ ion beam mediated foreign genes into rice. [Result] The implantation energy,dose,DNA concentrations and immersion time of DNA showed significant biological effects on the normal growth and development of DER10-04-01,in which the biological effects of implantation dose and DNA concentrations were relatively obvious. [Conclusion] The implantation energy,dose,DNA concentrations and immersion time of DNA were major factors showing important effects on the experimental result in ion beam mediated foreign genetic materials.展开更多

Methods: A cross-sectional study was conducted among IFFWs sampled from several joint- venture and private factories in Dongguan city. Results: Out of 175 sampled workers, 165 qualified for inclusion and the median age was 22. The results showed that the IFFWs had low levels of knowledge about HIV/AIDS, and held many misconceptions. Thirty three of 76 (43.4%) unmarried IFFWs had premarital sexual contact, and more than half of these contacts were one-night stands (54.5%) . More than one quarter of the women(25.9%) never used condoms, 49.4% sometimes used condoms and 24.7% used condoms every time. Twenty-eight women (31.8%) had an induced abortion because of an unexpected pregnancy. Fourteen (14.9%) had been infected with STDs, and four IFFWs(2.8%)had tried drugs before the interview. Conclusion: In order to empower the IFFWs in the city to protect themselves from HIV, and to contain the rapid spread of HIV in our province, targeted HIV/ AIDS health promotion programs should be urgently implemented among IFFWs in Dongguan city. The programs should be designed to improve the knowledge of HIV, to promote condom use, and to reduce risky behaviors.展开更多
