Assessment of the detergent wastewater quality

Constant rise in world population is creating main problem about health and removal of pollution due to industries and due to consumption products by humans is causing the need to increase cleaning of wastewater in world which has become the reason for new pollutants to enter environment, one of them is 'detergent'. Entry of wastewater to rivers and lakes creates eutrification, resident of non-biodegradable detergent and foaming. Such as this wastewater treatment is hardly to achieve therefore, identifying wastewater characteristic is necessary to choose the specific treatment method. This paper describes a study of the characteristic of Paksan Wastewater during a five-month period. The result of wastewater characterization show that the concentration of the organic water was very high, expressed as COD ranging from 6256-13040, MBAS ranging from 245-1120, phosphorus concentration and pH were also high, however, BOD concentration was low. Therefore, before subjecting it to biological reactor the high and varied organic loads should be reduced significantly by applying proper methods of pre-treatment, like advance oxidation process, coagulation and installation of equalization pond

Subclinical eating disorder, polycystic ovary syndrome- is there any connection between these two conditions through leptin- a twin study

The genetic property of subclinical eating behaviour (SEB) and the link between SEB and polycystic ovary syndrome (PCOS) has been studied before but the role of leptin within this connection has never been investigated. The objective of this study was 1). to study the genetic property of SEB. 2). To find a link between leptin, SEB and PCOS. One hundred and fifty four (77 pairs) female-female Iranian twins including 96 MZ individuals (48 pairs) and 58 DZ individuals (29 pairs) participated in the study. Clinical, biochemical and ultrasound tools were used to diagnose polycystic ovary syndrome. BITE questionnaire was filled out for subjects. Eight percent of subjects were diagnosed for subclinical eating disorder. No significant difference was found between intraclass correlation of MZ and DZ (z = 0.57, P = 0.569). Serum leptin level correlated significantly with bulimia score (P < 0.007). The mean (+/-SD) value for bulimia score was found to be higher among PCOS(positive) subjects (3.27 +/- 5.51) in comparison with PCOS(negative) subjects (2.06 +/- 4.48) (P < 0.001). The genetic property of subclinical eating disorder was not confirmed as shared environment might have played a major role in likeliness of DZ twins as well as MZ. Leptin is linked with both subclinical eating disorder and PCOS.
