Abstract

Electroplating waste water is considered to be harmful to health of animals. In the present study, we tested the hypothesis that electroplating waste water would suppress immune functions in Kunming mice. Twenty-six mice were randomly divided into the control group (n = 13) and the experimental group (n = 13), in which the latter drank electroplating waste water. We found that body mass and most organ wet masses (heart, lungs, liver, kidneys, stomach, caecum, colon, testes, epididymis, seminal vesicals) were not influenced by electroplating waste water. However, stomach with its content, small intestine, small intestine with its contents and colon with its contents were higher in the experimental group than in the control group. As expected, phytohaemagglutinin (PHA) response indicative of cellular immunity was suppressed by electroplating waste water. White blood cells, thymus and spleen mass were all not response to electroplating waste water. Taken together, electroplating waste water had different effects on distinct components of immune system in Kunming mice.

Highlights

Electroplating waste water is produced in the electroplating industries such as the machinery manufactured, light and electronic industries
Electroplating waste water increased the masses of stomach with its content, small intestine, small intestine with its contents and colon with its contents (Table 1)
Masses of immune organs and other organs were not influenced by electroplating waste water (Table 1)

Summary

Introduction

Electroplating waste water is produced in the electroplating industries such as the machinery manufactured, light and electronic industries. Due to its harmful components such as chromium, cadmium and cyanide and other. (2016) Effect of Electroplating Waste Water on Immune Function in Kunming Mice. Some researchers have reported the harmful effects of electroplating waste water in shrimps and fishes. Electroplating waste water has harmful influence on the embryos and juveniles of shrimps and fishes [3]-[6]. Many fishes died in a river near the city of Guanzhou in China in February 2006, which was mainly caused by electroplating waste water [7]. Influence of electroplating waste water on small mammals receives little attention
