The article is focused on estimation of Zinc in the roadside forages, and blood of buffaloes feeding on these forages. This study was carried out in Sargodha during December 2015 to January 2016 (winter) and May 2016 to June 2016 (summer). Five road sites (Mateela, Faisalabad roadside, Shaheenabad roadside, Bhalwal roadside and 50 chak) were selected from sampling of forages, soil and buffalo blood sample. Heavy metal analysis of all digested samples was done with atomic absorption spectrophotometer. Analysis of variance and correlation was done with two way ANOVA. This study regarding the accumulation of zinc in forages, soil and the buffalo blood would help the authorities to exactly determine the agents which are responsible for increasing pollution in the environment.

STUDI PENURUNAN KADAR LOGAM BESI (Fe) DAN LOGAM TEMBAGA (Cu) PADA AIR EMBUNG MENGGUNAKAN ADSORBEN NANOSILIKAABSTRAKPolusi limbah logam berat dalam air merupakan satu permasalahan lingkungan yang penting. Dalam mengatasi permasalahan tersebut dapat dilakukan purifikasi terhadap air tersebut. Metode yang dapat digunakan untuk purifikasi limbah sangat beragam salah satunya adalah absorpsi. Secara umum metode absorpsi telah banyak digunakan dalam purifikasi air limbah. Metode absorpsi dapat menurunkan kadar logam yang terlarut pada limbah. cair dengan cara menyerap logam-logam tersebut ke dalam permukaan absorbennya. Tujuan dilakukan penelitian ini adalah  untuk menurunkan konsentrasi logam besi (Fe) dan tembaga (Cu) menggunakan adsorben nanosilika. Penelitian ini menggunakan variabel bebas yaitu waktu pengadukan (20 menit, 40 menit, dan 60 menit). Hasil akhir filtrat air embung kemudian diukur absorbansinya menggunakan Spektrofotometer Serapan Atom. Berdasarkan hasil analisa menggunakan instrumen SSA diperoleh hasil bahwa tidak terjadi penurunan logam Fe maupun Cu. Dalam hal ini terjadi peningkatan konsentrasi dalam logam Fe maupun Cu, hal ini dikarenakan kurangnya waktu pengadukan dan pengaruh dari adsorben nanosilika.Kata Kunci: limbah, logam berat, nanosilika STUDY OF DECREASING METALS IRON (Fe) AND COPPER (Cu) ON EMBUNG WATER USE OF NANOSILICA ADSORBEN ABSTRACTHeavy waste pollution of heavy metals in the water is an important environment issue. To solve the problem, its can be purified the water. The methods that can be used for waste purification are very diverse, one of which is absorption. In general, the method of absorption has been widely used in wastewater purification. The absorption method can decrease dissolved metal content in the waste. liquid by absorbing the metals into the absorbent surface. Research has been conducted to reduce the concentration of iron (Fe) and copper (Cu) by using nanosilica adsorbent. This research used to independent variable that is stirring time (20 minutes, 40 minutes, and 60 minutes). The final result of filtrate embung water then measured its absorbance using Atomic Absorption Spectrophotometer (AAS). Based on the result of the analysis using SSA instrument, it is found that there is no decrease of Fe and Cu metals. There are several reasons for those problem such as due to lack of stirring time and the influence of nanosilica adsorbent.Keywords: Waste pollution, heavy metal, nanosilica

 Objective: Ulva reticulata is a marine edible green seaweed widely distributed along the coastal lines of India. The present study was designed to screen the phytochemicals and evaluate heavy metals content of U. reticulata collected from Rameshwaram, Tamil Nadu, India, in the perspective of assessing their therapeutic value and/or safety in relation to its uses.Method: The seaweed sample was subjected to extraction with solvents of different polarities (methanol, ethanol, acetone, chloroform, and petroleum ether) and screened for phytochemicals according to standard methods. Heavy metal analysis was also performed with the dried sample powder using inductively coupled plasma optical emission spectrophotometer (ICP-OES).Result: Preliminary phytochemical analysis revealed the presence of reducing sugar, proteins, flavonoids, glycosides, alkaloids, and anthraquinones. ICP-OES indicated the seaweed to contain relative amount of heavy metals in the order of iron (Fe) > chromium (Cr) > Zinc (Zn) > nickel (Ni) > copper (Cu) > lead (Pb) - cadmium (Cd) and is within the permissible limits set by the WHO/FAO, except Fe and Cr.Conclusion: The different solvent extracts of U. reticulata showed the presence of the number of phytochemicals. Furthermore, the present study has revealed the presence of heavy metals in U. reticulata which can be a representative picture of the dissolved metals in the aquatic phase.
