گزارش کار آموزی رشته مهندسی بهداشت محیط در شبکه بهداشت و درمان
چکیده: گروهی معتقدند كه عامل اصلی در تعیین سرنوشت و سلامت موجودات زنده توارث است و عده ای نیز اعتقاد دارند كه محیط نقش اصلی را به عهده دارد ولی جملگی بر این نكته اتفاق نظر دارندكه اثر عامل ارث هر قدر هم قوی باشد در محیط نامساعد خنثی می شود در حالیكه صفات ارثی در محیط مناسب پرورش یافته و بارزتر می شوند. محیط زیست مجموعه بسیار عظیم و پیچیده از عوامل گوناگونی است كه بر اثر یك روند تكاملی تدریجی موجودات زنده واجزای سازنده سطح زمین به وجود آمده است بنابراین در فعالیت های انسان تاثیر گذاشته و از آن متاثر می گردد. انسان در طی اعصار گذشته تاكنون همواره در ارتباط با محیط زیست اطرافش بوده و با گذشت زمان ب پیچیدگی و گستردگی این ارتباط افزوده شده است . امروزه با ازدیاد روز افزون جمعیت و نیاز به غذا ، توسعه ،شهر نشینی ، بهره برداری از منابع طبیعی و نیز توسعه صنعت و فراورده های صنعتی میزان دخل و تصرف انسان در محیط زیست افزایش یافته و باعث آلودگیهای خطرناك در مواد مورد نیاز انسان مانند خاك ، آب و هوا شده است. آلودگیها محیط زیست را برا زندگی انسان نامساعد ساخته و عواقب سویی را به همراه داشته است. در نتیجه برای كنترل آلودگیهایی كه توسط انسان در محیط ریست ایجاد شده و عواقب سوء ناشی از ارایه خدمات رشته خاصی به نام مهندسی بهداشت ضروری است.
