E-CommerceElectronic commerce, commonly known as e-

commerce or e-commerce, is trading in products or services using computer networks, such as the Internet.

Electronic commerce draws on technologies such as mobile commerce, electronic funds transfer, supply chain management, Internet marketing, online transaction processing, electronic data interchange (EDI), inventory management systems, and automated data collection systems.

Social Impacts of E-CommerceModern electronic commerce typically uses

the World Wide Web for at least one part of the transaction's life cycle, although it may also use other technologies such as e-mail.

1. The e-commerce has changed the relative importance of time, but as the pillars of indicator of the country’s economic state that the importance of time should not be ignored.

Social Impacts of E-CommerceNowadays, the transparent and real-time

information protects the rights of consumers, because the consumers can use internet to pick out the portfolio to the benefit of themselves.

The new economy led by the e-commerce change humanistic spirit as well, but above all, is the employee loyalty. Due to the market with competition, the employee’s level of professionalism becomes the crucial for enterprise in the niche market.

Distribution Channels of E-CommercePure-click or pure-play companies are those

that have launched a website without any previous existence as a firm.

Bricks-and-clicks companies are those existing companies that have added an online site for e-commerce.

Click-to-brick online retailers that later open physical locations to supplement their online efforts.

Water PollutionWater pollution is the contamination of water bodies (e.g. lakes, rivers, oceans

, aquifers and groundwater). This form ofenvironmental degradation occurs

when pollutants are directly or indirectly discharged into water bodies without adequate treatment to remove

harmful compounds

Sources Point sourcesPoint source water pollution refers to contaminants that

enter a waterway from a single, identifiable source, such as a pipe or ditch. Examples of sources in this category include discharges from a sewage treatment plant, a factory, or a city storm drain. The U.S. Clean Water Act (CWA) defines point source

Nonpoint sourcesNonpoint source pollution refers to diffuse contamination

that does not originate from a single discrete source.

Agriculture

CausesDisinfection by-products found in chemically disinfected 

drinking water, such as chloroformFood processing waste, which can include oxygen-demanding

substances, fats and greaseInsecticides and herbicides, a huge range of organohalides and

other chemical compoundsPetroleum hydrocarbons, including fuels (gasoline, diesel fuel,

jet fuels, and fuel oil) and lubricants (motor oil), and fuel combustionbyproducts, from storm water runoff[17]

Volatile organic compounds, such as industrial solvents, from improper storage.

Chlorinated solvents, which are dense non-aqueous phase liquids, may fall to the bottom of reservoirs, since they don't mix well with water and are denser.

TestSamplingSampling of water for physical or chemical

testing can be done by several methods, depending on the accuracy needed and the characteristics of the contaminant

Physical testingCommon physical tests of water include

temperature, solids concentrations

TestChemical testing Water samples may be examined using the

principles of analytical chemistry. Many published test methods are available for both organic and inorganic compounds.

Biological testing Involves the use of plant, animal, and/or

microbial indicators to monitor the health of an aquatic ecosystem

Positive & Negative Effects Of Technology On Our Lives

In the present globalized world, we are living in the

era of advanced technology. Every part of our daily

life is related to technology in one or other way

When compared with old days, we are having better facilities and even better luxuries with the help of increased technology.

The development of technology is not confined to any one sector and all the industries and different sectors of society are developing new technologies according to their needs and requirements.

Positive Effects of TechnologyThere are so many advantages with improved

technology in our daily life. With the help of mobile technology we are able to

talk to our friends and relatives who are living far from us.

With the help of internet, we are able to learn new things and online courses etc.

With the help of aviation technology we are able to reach distant places within hours which took years of time to reach in old days.

We are using the all natural resources available for making our life better.

Negative Effects Of Technology On Our LivesInstead of taking care personally we are sending sms

or giving a call on important occasions which were attended personally in olden days.

With the use of same internet children are getting addicted to online games and their physical activities and exercises are becoming considerably less.

The same social networks are creating rivalry between best friends and couples are getting divorced.

The same aviation technology is giving health problems for their workers and creating serious environmental threats.

With the heavy usage of fertilizers soil is losing its natural fertility and several varieties of plants became extinct.

Conclusion

Technology is like a coin which has both positive and negative sides. We are the deciders and we have to choose how to use it. The usage of technology for over exploitation of resources should be always avoided. If we use it for positive things, it will have positive effect of our lives and vice versa. Nobody would oppose the development of technologies in any sector but the developments should be in a positive way and they should not have any negative impact on present or future generations.
