The treatment of Pentachlorophenol Sodium (PCP-Na ) industrial waste water, in which the PCP-Na concentration is 10, 000 ̄ 15, 000 mg/L and CODcr is 11, 000 mg/L, is carried out with CHA-111 polymeric adsorbent.
A 16.2? L anaerobic baffled reactor (ABR), with five compartments, was used to treat wastewater containing glucose and pentachlorophenol sodium (PCP Na). The reactor was operated at temperature of 35±1℃, HRT of 24 h and the influent COD of 1100—1200?
Conclusion 25 to 100 mg/kg pentachlorophenol sodium could inhibit the humoral immunity and 100 mg/kg could inhibit the macrophage function after once treatment. Whereas the cellular immunity was not influenced by current treatment.
Methods Pentachlorophenol sodium was gavaged to mice once time and the dosages of pentachlorophenol sodium were 25,50 and 100 mg/kg. The changes of immume function were observed at 3,24 and 48 hours after pentachlorophenol sodium treatment. Cellular immunity was measured through T lymphocyte proliferation;
A teratological study was made in mice.Paecilomyces gunnii was administered by gavage to pregnant mice at dose levels of 0.66,2.0,6.0g/kg/day on gestation days from six through fourteen.The gain in the maternal body weight and the anomalies in the embryon′s shape,viscera and skeleton revealed no statistically significant differences between the group treated by paecilomyces gudii and the control group treated by tap water.In conclusion,paecilo myces gunnii showd no embryotoxie and teratogenie effects in mic...
Momordica charantia extract was used in 23 pregnant mice by gavage to determine whether it has embryotoxic and teratogenic effects. The mice were divided into two groups (13 mice in dose of 2.5ml/kg/d10, mice in dose of 15ml/kg/d). In conclusion: In lower dosage group, M. Charantia Lnn extract showed no embryotoxic and teratogenic effects. The live mbryo number, embryo weight and the anomalies of embryo shape and viscera in high dosage group revealed no statistically significant differences, as comparing wi...
In order to study the molluscicidal effects of Luomiecide (50% wettable powder of ethanolamine salt of niclosamide), the experiments were carried out in the laboratory and field. The results showed that in the laboratory, 90-100% of snails were killed when they were immersed in Luomiecide with concentrations of 0. 2-0. 5mg/L for 48 hours. When the drug was used as spray in the field. the snail death rates were 73. 33-89. 72 % at the dosage of 2g/m2 and 86. 9-93.75% at the dosage of 3g/m2 for 3-7 days. The s...
