Lead Content Analysis (Pb) On Snack Road Ir. H. Juanda City Jambi increasingly proliferation of street vendors snack on the street where the activity is quite crowded, allowing snacks that are sold can be contaminated by lead (Pb) coming from motor vehicle fumes. This study aims to determine the content of lead on street snacks and compared with the maximum limit of lead food in snack foods that have been determined by the Director General of POM in the decision of Director General of POM Number HK.00.06.1.52.4011 Year 2009 on the maximum limit of metal contamination in food that is 0,25 ppm. This research is a descriptive research that gives a picture of lead content in snack. The study was conducted on traders selling fried foods at Street H. Juanda Jambi City. Sampling using total sampling technique where for each place of sale taken three kinds of fried foods such as fried bananas, tofu contents and bakwan. Examination of laboratory test of Environment Department (DLH) Province Jambi Year 2017 got big parameter of S02 equal to 19.5 μg/nm3 whereas standard quality standard set PP. 41 of 1999 on the ambient air quality of 900 μg/nm3, for the parameter N02 of 23.0 μg/nm3, while the standard quality standard set PP. 41 of 1999 on ambient air quality of 400 μg/nm3, for lead parameters (Pb) with the result 0.082 μg/nm3, while the standard quality standard established PP. 41 year 1999 About ambient air quality of 2 μg/nm3 and dust parameter with result 80 μg/nm3 while standard quality standard set PP. 41 of 1999 on ambient air quality of 230 μg/nm3. The content of timbale in banana snack food is 0,0850%, for food bakwan is 0.0008% and for food tofu content is 0,1505% so it has not exceed the maximum limit of metal contamination in food which has been determined by Dirjen POM in decision of Dirjen POM Number HK.00.06.1.52.4011 Year 2009 is 0.25 ppm.Keywords : Ambient Air Quality, Lead (Pb), snack food

This study aims to determine the level of air pollution based on gas waste and ambient air quality, so it can be known which chimney releases waste gas the most and the least. It also knows which villages are most affected and safest from gas waste from PG Mojopanggung. Weighted Product method is used to calculate the level of air pollution. The results showed that from the side of the gas waste, the Stork I Boiler Chimney is the most discharging chimney gas waste, while the value of pollution by chimney kettle in PG Mojopanggung all does not exceed the standard quality that has been determined. Conversely, in terms of ambient air quality, Jatimulyo village is the village most affected by gas waste from PG Mojopanggung. There are some air pollutants that exceed the specified quality standard but not too much difference. To overcome the air pollutant that exceeds the quality standard, PG Mojopanggung performs the gas waste treatment and several other solutions.

According to the information of air quality which published by the urban air quality real-time publishing platform, the concentration characteristics of PM10 and PM2.5 were studied in Kunming (KM), Changsha (CS), Hangzhou (HZ), Shanghai (SH), Harbin (HEB), Beijing (BJ), Wuhan (WH) and Guangzhou (GZ). The results show that the concentrations of PM10 and PM2.5 exceeded the Ambient Air Quality Standard (GB3095-2012) in varying degrees in March, 2013. The concentrations of PM10 in Wuhan is the highest, reached 164μg/m3, exceeded the standard by 9.3%; the concentrations of PM2.5 is much higher in Wuhan, Changsha and Beijing, the average concentrations were 96μg/m3, 103μg/m3 and 110μg/m3, exceeded the standard by 28.0%, 37.3% and 46.7% respectively. The correlation of PM10 with PM2.5 in most of these cities was good in March. The correlation analysis of pollutant with meteorological factor in Hangzhou, Shanghai, Beijing and Guangzhou was also studied, the results show that the concentrations of PM10 and PM2.5 are weakly positive correlation with temperature in the four cities, negative correlation with relative humidity without Beijing, and negative correlation with wind speed.

The purpose of this research are to analysis air quality and dust impact to people that came from factory activities at residential area around factory location of PT. Semen Padang. Measuring of air quality conducted in 3 residential area that are Komplek RW 1, RT 3 Batu Gadang district, Perumnas Indarung RW. VII, and housing of UNAND Blok D Gadut, using Personal Dust Sampler. The result is respirable dust concentration at housing complex RW. 1 RT. 3 Batu Gadang district that is 0,33 mg/m, the Perumnas Indarung RW.VII that is 0,55 mg/m along with housing of UNAND Blok D Gadut that is 0,44 mg/m. Concentration of dust respirable at all are still below ambient air quality standard that exist on PP RI No. 41 Tahun 1999, 3 mg/m. Based on quesioner and puskesmas data proximate with use univariat analysis, negative impact who feels people are impact of health is eyes irritation disease and impact of environment especially community-owned material.

Jharia Coalfield

India is in the list of fastest growing countries of the world. India's energy needs are also increasing due to population and industrial growth for improving quality of living style. In India, coal is major input infrastructure industries for example Power plants, Steel plants and Cement industries. India’s 52% of primary energy is coal dependent1. 66% of India's power generation depends upon coal production1. Jharia Coalfield (JCF) is falling in the Lower Gondwana Coalfields of India. The area of the JCF is about 450 km2. It is important for the major supply of precious coking coal required for steel plants in India. It is located in Dhanbad district of Jharkhand state of India, The latitude is 23° 39' to 23° 48' N and longitude is 86° 11' to 86° 27' E for the Jharia coalfield. Based on environmental parameters, all the 103 mines of BCCL have been grouped under 17 Clusters. A cluster consists of a group of mines with mine lease boundary lying in close vicinity and includes-Operating mines, Abandoned/ closed mines and proposed projects.The focused study area is in the western part of the Jharia coalfield is named as Cluster XV group of mines of BCCL consists of four mines, Kharkharee Colliery (UG), Dharmaband Colliery (UG), Madhuband Colliery (UG) and Phularitand Colliery (UG) .The present study was carried out with the objective to measure the ambient air quality of the study area with reference to particulate matter (SPM, PM10 & PM2.5). Ambient air monitoring results have shown that the observe air quality were found within the limit prescribed by MoEF / CPCB. It may due to Underground mines as there are pollution causing lesser activities involved in the UG mining process compared to opencast mining. Implementation of Master plan for Jharia coalfields for environmental management has also improve the air quality in the area10,11.

Pm2.5 Concentration

PM2.5 pollution causes great health hazards, which will finally result in much economic loss. In China, it is first time to take PM2.5 as a general limitation factor in the revised version of "Ambient Air Quality Standard". In this work, we take Beijing as investigation objective, choose five kinds of typical health impacts, and make rough economic estimation of the potential benefits from the decrease of PM2.5 concentration through the epidemic-doses model in a quantitative point of view. Assuming the PM2.5 pollution is controlled well and satisfies the requirement of Grade 2 and 1 of new standard, 1681 and 2269 million Yuan will be saved in Beijing considering only health aspects. So it is necessary to take PM2.5 into the new ambient air quality standard as a general indicator, which is overall beneficial for environment and economy.
