This paper deals with the effect of photobiomodulation (PBM) on Daphnia magna S. and their sensitivity to cadmium sulfate, a known high toxic pollutant. In a first series of experiments, the effect of different He-Ne laser fluences irradiation (range 0.9-4300 mJ cm ) on the fertility of both parent and filial generations (F1-F3) of the crustacean was studied. It was found that PBM in some cases significantly influenced the fertility of both irradiated crustaceans and their nonirradiated offspring. By selecting two fluences (9 ± 2 mJ cm reducing fertility and 4.3 ± 0.9 J cm increasing it), the effect of these on toxicity of cadmium sulfate was evaluated. These experiments have shown that prior irradiation with low-intensity light of a helium-neon laser with 632.8 nm wavelength can change the sensitivity of aquatic organisms to toxin cadmium sulfate. The degree and direction of changes depend on the toxicant concentration and the irradiation dose.
本文研究了光生物调节（PBM）对大型溞（Daphnia magna S.）及其对硫酸镉敏感性的影响。硫酸镉是一种已知的高毒性污染物。在一系列实验中，研究了不同氦氖激光辐照剂量（范围 0.9-4300 mJ cm ）对甲壳类动物亲代和子代（F1-F3）生育能力的影响。结果发现，在某些情况下，PBM 显著影响了辐照甲壳类动物及其未辐照后代的生育能力。通过选择两种剂量（降低生育能力的 9 ± 2 mJ cm 和增加生育能力的 4.3 ± 0.9 J cm ），评估了它们对硫酸镉毒性的影响。这些实验表明，用波长为 632.8nm 的氦氖激光进行低强度光辐照可以改变水生生物对毒素硫酸镉的敏感性。变化的程度和方向取决于毒物浓度和辐照剂量。
