The impact of the industrial pollution on the environmental world

Industrial Pollution

Introduction

Many industrial manufacturing processes use or produce chemicals that may harm people’s health or the environment. For instance, paper pulp bleaching uses chlorine (Cl), while power generation using coal creates acid rain. Although factory chimneys producing black smoke are rare in most industrial nations these days, invisible pollutants may still enter the air, ground, or surface water. Even at low levels, they may cause harm, particularly in the long term.

Environmental law now requires industry to take more responsibility for any emissions that could harm the environment. Ongoing independent monitoring of the air and water supply are necessary to check for any breaches of legislation. Cleaner technologies, including green chemistry, can reduce production of pollutants from their source. However, there is still a legacy of industrial pollution from the past with contaminated sites that have residues of long-lasting chemicals such as polychlorinated biphenyls, or PCBs (C12H10-xClx), which were once very widely used Any modern industry has the potential to produce some pollution. Often this is in the form of wastewater that has been used in processing or for cleaning equipment, and has thereby become contaminated with pollutants. Some byproducts of industrial processes are polluting, such as the toxic dioxins (C4H4O2) produced in the manufacture of certain herbicides, or the acidic sulfur dioxide (SO2) produced by burning coal. The paper and pulp industry has attracted criticism from environmental campaigners in the past over its use of chlorine as a bleaching agent. The chlorine combines with organic compounds in the wood to make a number of hazardous organochlorine compounds, including furans (C4H4O) and dioxins. There has been a move within the industry toward chlorine-free technology, but this is not yet universal.

Aggregation, choose Count.

This chart shows us a different view o

This chart shows us a different view of the data. The chemical sector appears to have the highest number of facilities, while the Metal Mining sector has relatively low facilities. This may indicate that metal mining facilities have high emissions, or that a few facilities have very high emissions and are skewing the chart. You’ll explore this more at the end. For now, you’ll continue to explore total emissions.

6. In the Chart Properties pane, for Aggregation choose Sum.

You’re also interested in potentially dangerous chemicals, so you’ll split the industry emissions based on whether they are classified as carcinogenic or not.

7. In the Chart Properties pane, for Spit By, choose Carcinogen.

It looks like the majority of chemicals emitted are non-carcinogenic.

Next, you’ll make a bar cart of emissions by state.

8. Right-click Toxic Release Inventory > Create Chart > Bar Chart.

9. In the Chart Properties pane:

• For Category or Date, choose ST.
• For Numeric Fields, choose OnSiteReleaseTotal.

It looks like Alaska has the highest emissions, but its hard to tell which state has the lowest. You can use the Sort functionality to rearrange the bars from highest to lowest, based on their y-axis, or sum of pollution value.

10. On the Bar Chart, click Sort > Y-Axis Descending.

The Northern Marianna Islands (MP) have the lowest total emissions.

Next, you’ll create a bar chart for counties. At first, this chart will appear cluttered, but when you use the chart filtering options it will become cleaner.

11. Right-click Toxic Release Facilities > Create Chart > Bar Chart.

12. In the Chart Properties pane:

• For Category of Date, choose County.
• For Numeric Fields, choose OnSiteReleaseTotal.
• For Aggregation, choose Sum.

It looks like one county has extremely high emissions. You’ll zoom to that county to find out more.

13. In the Bar Chart pane, ensure that you’re in Select Mode.
