Macam Pencemaran Menurut Bahan Pencemarnya


Dalam postingan sebelumnya, kita sudah mengenal berbagai macam pencemaran menurut tempat terjadinya. Dalam postingan kali ini kita akan mempelajari berbagai macam pencemaran menurut bahan pencemarnya.

Berikut adalah macam pencemaran menurut bahan pencemarnya yaitu : 

1.    Pencemaran Kimiawi
Pencemaran kimiawi adalah pencemaran yang disebabkan oleh bahan/ zat kimia. Zat kimia ini bisa berasal dari limbah industri, limbah rumah tangga ataupun yang berasal dari penggunaan pestisida DDT yang berlebihan. Zat kimia yang berasal dari limbah pabrik yang merupakan logam berat misalnya Pb (timbal), Hg (Air raksa), Cd (kadnium), Zn (seng), Cr (kromium), dan Ni (nikel). Limbah rumah tangga yang mengandung bahan kimia adalah penggunaan detergen.

Zat kimia yang lain penyebab pencemaran adalah penggunaan pestisida DDD yang berlebihan. DDT (Dikloro Difenil Trichlorothan) mengakibatkan pencemaran tanah dan pencemaran air.

2.    Pencemaran fisik
Pencemaran fisik adalah pencemaran yang disebabkan oleh benda-benda fisik yang bisa berupa bahan padat, cair dan gas. Zat cair yang dapat menyebabkan pencemaran misalnya limbah rumah tangga, keluarga, dan limbah pabrik. Zat padat yang menyebabkan pencemaran adalah kaca, logam, botol, karet, kaleng-kaleng bekas dan plastik. Sedangkan gas yang menyebabkan pencemaran misalnya asap pabrik, asap rokok, dan asap kendaraan bermotor.

3.    Pencemaran biologis
Pencemaran biologi adalah pencemaran yang disebabkan oleh bahan yang  berupa mikroorganisme penyebab penyakit, misalnya Escherichia coli, Entamoeba coli, dan Salmonella thyposa. Kebanyakan mikroorganisme tersebut dapat menyebabkan penyakit perut.

    Hi just wanted to give you a brief heads up and let you
    know a few of the images aren't loading correctly. I'm not sure why but
    I think its a linking issue. I've tried it in two different browsers and both show the same results.

    I think that what you posted was very logical.
    However, what about this? what if you wrote a
    catchier title? I am not saying your content is not good.
    , however what if you added a post title that grabbed people's attention? I mean "Macam Pencemaran Menurut Bahan Pencemarnya" is kinda boring. You could peek at Yahoo's home
    page and watch how they create article headlines to get people
    interested. You might add a video or a related picture or two to get people interested about everything've got to say. Just my opinion, it might bring your posts a little livelier.
