谁能帮我翻译一段话呀，谢谢啦

多氯联苯（PCBs）是全球性的持久性有机污染物中的一种，这些物质对贻贝的种群繁衍、群落结构造成伤害，甚至威胁人类健康。PCBs对人体健康存在很大的潜在威胁，目前国内关于PCB的研究工作比较多。但究竟PCB会对人体或动物体造成多大的伤害？这类研究的信息还比较的缺乏，而且目前PCBs虽然暂时还未给我国水产品出口造成损失,但将来有可能被发达国家利用作为限制我国水产品出口的手段。在本实验中，主要以PCB中的BaP作为研究对象。本实验通过对BaP对贻贝受精卵，胚胎等早期生物体的影响，主要研究当前大家关心的环境雌激素BaP对贻贝胚胎毒性作用，从而为环境安全评估和保护人类健康打下一定的基础。

就翻译上面的，是我论文的摘要，哎呀英文太蹩脚，老翻不好，谢谢啦，有分加哦。

Construction of effective internal control system to ensure that the quality of accounting information, for improving the corporate governance structure and information disclosure system, the protection of the legitimate rights and interests of investors and to ensure the effective functioning of capital markets has a very important significance. Kai-yan, as a single shareholder of the private enterprises, with very good profitability, and sustained ability to generate cash flow, financial indicators alone, said small and medium-sized panel market has reached the standard, so the company developed a three-year period of capital markets strategy Login . But as a lack of corporate governance structure and management team, professional managers of private enterprises, how to improve its internal control, and listed companies to meet their demands? This is the motivation of this paper, and goals.
In this paper, from sheathed ex internal control some of the problems as a starting point, ask questions; and then introduce the theoretical circles both at home and abroad on the development of the theory of the internal control process, highlighting the internal check and internal control structure to the overall internal control framework of the evolutionary process; after capital markets at home and abroad to introduce the internal control requirements; to the use of COSO internal control system for the definition of control environment, risk assessment, control activities, information and communication, supervision, such as detailed analysis of five ex armor companies that exist in internal control the main problem; the final use of the five elements of COSO framework of Kai En construction company's internal controls and make recommendations for improvement.
In this paper, the overall COSO internal control framework, that is, the five elements of internal control system, a complete analysis of a company's internal control system, based on the results of research in this article on the suit of TU's all-round improvement of the implementation of internal controls, will be the level of corporate governance a larger raise. In addition I currently serve as ex-kai, director of the company's financial position, you can contact the company a comprehensive system of internal control, and can be combined with day-to-day work-related control measures can be implemented to test the theory and methodology of the appropriate. At the same time, the results of research on corporate governance in other medium-sized family businesses do not sound very good to improve the internal control reference.

Key words: control of the internal control environment to control the activities of risk assessment
Add: Do not use software to translate, I can polychlorinated biphenyls (PCBs) is a global persistent organic pollutants in one of these substances on the mussel population reproduction, the community structure damage, and even a threat to human health. PCBs on human health there is great potential threat, current research work on the PCB more. But PCB on humans or animals caused much harm? These studies also compared the lack of information, and is not yet PCBs although the export of aquatic products to China's loss, but the future may be developed as a restricted use of the means of China's export of aquatic products. In this experiment, the main PCB of BaP in the study. Through this experiment, mussels BaP on fertilized eggs, embryos, such as the impact of early organisms, the main research we are all concerned about the current environmental estrogens BaP toxic effect on the mussel embryos in order to assess the environmental safety and protection of human health and lay a foundation.
