Aim & Scope

Environmental Analysis Health and Toxicology (EAHT) is an open access, peer-reviewed, online journal that receives manuscripts on the fields of research, policy, and teaching of environmental analysis health and toxicology. The journal is published online and includes original articles, reviews, meeting reports, brief reports, case reports, investigation reports, special topics, editorials, and letters. EAHT is formerly known as Environmental Health and Toxicology (2011-2019) and Korean Journal of Environmental Toxicology (1986-2010) and has a 34 year history of publication in the field of environmental analysis, health and toxicology with peer review process. EAHT is an official international journal of The Korean Society of Environmental Health and Toxicology/Korea Society for Environmental Analysis (KOSEHT) and the Korean Society for Environmental Analysis (KSFEA). It is also supported by the Korean Federation of Science and Technology Societies (KOFST) Grant funded by the Korean Government. EAHT has multidisciplinary areas of environmental analysis, health and toxicology, including chemical and biological analysis of environmental contamination, ecotoxicology and risk assessment, environmental chemistry, human toxicology and risk assessment, environmental epidemiology, and environmental exposure assessment. EAHT considers manuscripts that have not been published previously (except as an abstract), and are not being considered for publication elsewhere. A paper presented at a scientific meeting may be considered if it has not been published in full in a proceedings or similar publication. Any closely related manuscript either published, in press, or under review must be sent via e-mail to the journal office at the time of the submission to EAHT. This will allow for a full and fair evaluation of the independent contribution of the submitted paper. EAHT is indexed/tracked/covered by PubMed, PubMed Central, Scopus, ScienceCentral, KoreaMed, KoMCI, Directory of Open Access Journals, and Google Scholar.

    In this study, it was examined the toxic effects of combination of buprofezin and carbaryl on hematological, biological and enzymetic parameters in rats. The administration of buprofezin or carbaryl both induced the tissue content of cytochrome P-450 and furthermore, the combination of the both increased significantly the liver content of cytochrome P-450 in rat. But cytochrome P-450 and NADPH -cytochrome c reductase activities in kidney were slightly increased. Administration of carbaryl and combination of the both also significantly increased hepatic aniline hydroxylase activity. In addition, in the combination group, glucose-6-phosphatase and lipid peroxidase activities were changed in the rat liver. Furthermore, cholinesterase was inhibited in rats treated with carbaryl or the combination of buprofezin and carbaryl. The above results suggested that the combined administration of buprofezin and carbaryl can induce more toxic effects than the single administration of buprofezin or carbaryl.

    Effect of Synethrin on the Toxicity of Dichlorvos in Rats. Hematological, biological and enzymatic effects were investigated in rats treated with DDVP and synethrin. Mutagenicity was also examined. In serological analysis, LDH and ALP were more significantly increased in rats treated with the mixture of DDVP (10mg/kg) and synethrin (250mg/kg) than with either DDVP or synethrin. DDVP alone slightly increased cytochrome P-450 in the liver while synethrin or the mixture decreased it. Lipid peroxidation was significantly increased in the liver when rats were treated with both DDVP and the mixture. Cholinesterase activity was significantly decreased in the liver and serum when treated with DDVP as well as with the mixture. In mutagenicity test, DDVP was shown to be weakly positive to TA 97a, TA 100 and TA 102, but negative to TA 1537. Synethrin showed negative in all strains tested. These results suggest that the mixture of DDVP and synethrin increased the toxicities but not the mutagenicity.

    BPMC (2-Sec-butylphenyl N-methylcarbamate) was treated at the level of 100mg/kg/day in oral administration for 12th days in rat. It was investigated not only that the hematogram and the serological parameters, but also the content of cytochrome P-450, the activity of TBA, glucose-6-phosphatase, cholinesterase and carboxylesterase in rat. The results were as follows: The hematogram was not found any alteration but the value of AST, ALT, LDH and the content of glucose in serum were significantly increased compare with that of control group. The content of cytochrome P-450 in liver was increased significantly on the contrary cytochrome P-450 in kideny and NADPH-cytochrome c reductase in liver and Kidney were not significantly increased. After the final 12th day, the value of TBA and the activity of glucose-6-phosphatase appeared to the tendency of increasement in the liver. The activity of cholinesterase and carboxylesterase both in serum and liver were decreased. Especially the activity of cholinesterase was more significantly decreased. It was conclusion that the function of this insectivide should be due th the inhibition of cholinesterase activity.

    Recently, concerns of water pollution and health risks caused by synthetic detergents have emerged, as the use of various detergents has increased It has been suggested that some surfactants are cocarcinogens. The surfactants tested were linear alkylbenzene sulfonate, sodium lauryl sulfate, polyoxyethylene sorbitan monooleat (tween 80), and the mutagens were 1-nitropyrene, N -methyl- N'-nitro-N -nitrosoguanidine, benzo (a) pyrene, and aflatoxin B$_1$. This study was undertaken to investigate the effects of surfactants on the activity of mytagens using the Ames mutagenic assay with Salmonella typhimurium TA98, TA100. The results were summarized as follows: 1. The surfactants have no mutagenic activity of themselves. 2. Higher doses of surfactants than 100 $\mu\textrm{g}$/plate reduced the number of revertants. It is assumed that the reduction would inhibited cell growth. 3. When the comutagenic ratio is defined as the ratio between mutagenic activity itself and the activity with mutagen and surfactant (drinking water quality standard), LAS showed the comutagenic ratio 0.86-1.17 and SLS 0.74-1.10 as well. According to the comparisons, it could not be recognised for the comutagenicity of drinking water quality standard of surfactant. 4. As increasing the amount of mutagens, the designated amount of surfactant did not affected the mutagen's activity statistically. From the above result, syunthetic surfactants do not present mutagenicity and comutagenicity in the microbial assay.

    Physical compositions of solid waste in Wonju, shopping area were investigated with combustibles 78.13% (papers 35.89%, foods 14.41% etc.) incombustibles 21.87% (glass and ceramics 11.02%, metals 6.0% etc.) in 1991, solid waste in apartment area were investigated with combustibles 84.27% (foods 34.29%, papers 22.58% etc.), incombustibles 15.73% (glass and ceramics 8.77%, metals 4.85% etc.) and residence area were characterised with combustibles 70.37% (foods 33.55% , papers 10.53% etc.) and incombustibles 29.63% (ash of briquet 17.29%, glass and ceramics 7.49% etc.). Water qualities of a leachate from municipal landfill of Wonju city were analysed pH 8.0~8.4, total suspended solid 102~140 mg/1, CN￣ 0.003~ 0.008 mg/1, NO$_2$-N 0.108~0.294 mg/1 and phenols 0.46~1.12 mg/1. Volume of the leachate for 20% methemoglobin formation were 0.2~0.4 mg/ml in Octever, 0.3~0.4 ml/ml in December sampling, 0.2~0.3 ml/ml in St.1 and 0.4 ml/ml in St.3.
