Life-cycle toxicity of 4-nonylphenol to medaka (Oryzias latipes).
We studied the chronic effects of 4-nonylphenol (4-NP) on reproductive status of medaka (Oryzias latipes) over two generations of continuous exposure. The exposure study of the parental (F0) medaka was begun on embryos within 24 h postfertilization and continued with monitoring through embryological development, hatching, posthatch survival, growth, sexual differentiation, and reproduction unde...
متن کاملPotential for 4-n-nonylphenol biodegradation in stream sediments.
The potential for in situ biodegradation of 4-nonylphenol (4-NP) was investigated in three hydrologically distinct streams impacted by wastewater treatment plants (WWTPs) in the United States. Microcosms were prepared with sediments from each site and amended with [U-ring-(14)C]4-n-nonylphenol (4-n-NP) as a model test substrate. Microcosms prepared with sediment collected upstream of the WWTP o...
متن کاملFate of 4-nonylphenol in a biosolids amended soil.
The fate of the endocrine disrupting compound 4-nonylphenol (NP) in an agricultural soil amended with biosolids was assessed in a greenhouse study. A biosolids with a total NP concentration of 900 mg kg(-1) was incorporated into the 4 cm surface layer of soil columns at an agronomic rate equivalent to 1.7 kg m(2). Half of the columns were planted with Triticum aestivum L., red hardy winter whea...
متن کامل4-nonylphenol-induced toxicity and apoptosis in Hydra attenuata.
Effects of 4-nonylphenol (4-NP) on the morphology and survival of the cnidarian Hydra attenuata were studied under acute exposure conditions. The lethal concentration value inducing 50% mortality after 96 h was 97.5 +/- 20 microg/L, whereas the lethal concentration value inducing 10% mortality after 96 h was 64 +/- 25.5 microg/L. The no-observed-effect concentration based on morphological crite...
متن کاملتهیه، شناسایی و ارزیابی فعالیت کاتالیزگری نانوساختارهای فلز-آلی FeIII(OH)[O2C-C6H4-CO2] در سنتز پیرازولوپیرانوپیریمیدین‌ها
در این پژوهش، نانوساختار چارچوب فلز-آلی FeIII(OH)[O2C-C6H4-CO2] با نام تجاری MIL-53(Fe) به عنوان یک کاتالیزگر بسیار فعال برای تهیه مشتقات پیرازولوپیرانوپیریمیدین مورد استفاده قرارگرفت. به منظور تهیه نانوساختار MIL-53(Fe) از FeCl3.6H2O و اتصال دهنده ۱و۴ بنزن دی کربوکسیلیک اسید در حلال دی متیل فرمامید استفاده شد. کاتالیز...
