In the study of UV absorbing test, polyhydroxy substituted N-benzoylserotonin derivatives (compound 1-10) shows better ability to absorb UV and shows wider range of absorbing UVB than control group, octyl salicylate. With respect to octyl salicylate, octyl salicylate can abosorb the highest wavelength up to 306 nm under UVB (wavelength ranges 280 nm ~320 nm), and the ε is 4.03 × 103 ㎝-1M-1. However, the ε of polyhydroxy substituted N-benzoylserotonin derivatives (compound 1-10) under 306 nm range 4.14 × 103 ~ 11.45 × 103㎝-1M-1. It is reasonable that the compounds in this study can not only absorb the individual wavelength amoung the wavelenght of UVB, but also absorb wider range of wavelength.

在紫外线可见光吸收测试结果显示,相较於对照组水杨酸辛酯在UVB波长(280 ~ 320 nm)范围最大吸收波长为306 nm,其莫耳吸收系数为4.03 × 103 ㎝-1M-1,而多羟基取代之N-色洛冬宁苯甲醯胺衍生物(化合物1 ~ 10)在306 nm的莫耳吸收系数介於4.14 × 103 ~ 11.45 × 103㎝-1M-1,其吸收紫外线的效果皆优於对照组水杨酸辛酯,且其在UVB波长的范围吸收波长的光谱也较宽广,可知每个化合物并非只是对UVB波长范围内的单一波长有吸收度,而是对UVB波长范围具有较宽广的光谱吸收。

Ultraviolet Scorpion, 1978 Photograph by Bruce Dale Nocturnal crawler, a scorpion remains well camouflaged under a flash-light's beam, but fluoresces in ultraviolet light , a reaction that remains a mystery to scientists.

意译:紫外线的蝎子。夜间爬行者,一只蝎子很会伪装在手电筒的光线,但是发荧光的紫外线,一种反应遗留一种神秘的事物留给科学家。

The influences of environmental factors on the abiotic methylation were studied. The biggest production of methylmercury was found after 2 days of incubation in presence of FA. The rate of production of methylmercury depends upon temperature. In presence of FA from sediment, the biggest production of methylmercury was found under 40℃. In presence of FA from soil, production rate increases with temperature. The biggest production of methylmercury was found when solution pH was 2 and 4 in presence of FA from sediment and soil, respectively. Increase in concentrations of inorganic mercury and FA solution causes an increase in the production of methylmercury. Under irradiation with ultraviolet ray, blacklight lamp as well as natural light, methylation is stimulated, especial for irradiation of ultraviolet light.

环境条件对汞甲基化作用的影响研究得出,在底泥和土壤FA体系中甲基汞产量均在反应2天后达到最大值;在底泥FA体系中汞的甲基化在反应温度为40℃时产量最大,而在土壤FA体系中,甲基汞产量在10~60℃之间随反应温度升高而增加;底泥和土壤FA体系中汞的甲基化分别在pH值为2和4时最大;甲基汞产量均随无机汞浓度和腐殖质浓度的增加而增加;紫外线、黑光灯和自然光照射都可促进甲基汞的生成,紫外线的作用尤其明显。
