Abstract Air
is a carrier of microorganisms and various pollutants, as well as a large
number of microorganisms such as molds, bacteria, germs, and viruses, which
are estimated to be important as a directory of cleanliness envisioned for
any particular environment.This study was started
during 15th December 2021- 15th March 2022, to assess the indoor air
quality concentrations in Lucknow households, including PM2.5 and microbial
contaminants (the eleventh most populous city). Microbial samples were
collected from selected households using exposed Petri plates with (MacConkey agar) media and processed for the growth of
microbial contaminants. Their bacteria identification media plates were
incubated for 24-48 hours at 37 degrees Celsius.The
presence of bacteria was determined using the gram staining method, and PM2.5
was measured using an APM 550 medium volume sampler (Envirotech)
at a flow rate of 17.57 lpm with a GF/A filter
paper diameter of 47mm for 24 hours. The data revealed that PM2.5
concentration was highest at roadside for outdoors and indoors. The lowest
indoor/outdoor (I/O) were found at roadside houses which
was believed to be due to highconcentrations
of outdoors which was believed to be due to of heavy diesel generators, trafficof vehicles and closed windows, whereas I/O was
highest at planned houses due to indoorsources and
open windows for ventilation. Keywords: Particulate matter, indoor air pollution, bacteria,

(2022) A review of E-waste management in India for environment

Abstract E-waste
is one of the newer pollutants nowadays that is attracting attention from
people all around the world. The international community has severe concerns
about managing e-waste. Its pollution affects both wealthy and developing
nations, not only India. There are rules and regulations imposed by the
Indian government if there is no particular legislation on e-waste. The most
recent implementation of the government’s plan, the E-waste (Management)
Rules, 2016, offers a chance to examine the current e-waste management
procedure and assess its efficacy. Different laws covering various
environmental challenges are what makes India’s environmental regime special.
The Water (Prevention & Control) Act of 1974 and the Air (Prevention
& Control) Act of 1981 were both passed by the Parliament to prevent and
control water and air pollution, respectively. The Environment (Protection)
Act of 1986 is a piece of enabling legislation that was created to address
environmental protection concerns in a comprehensive manner. The E-waste
(Management and Handling) Rules, 2011, which were created under this Act of
1986, were replaced by the Rules of 2016. There are several concerns that
demand careful thought, identification, and a compelling need for compliance.
The issues relating to dishonest merchants, unethical business practices, and
some modifications made by the new Rules on e-waste disposal need to be
thoroughly examined. When new and advanced technology is developed, individuals
frequently abandon electronic equipment, especially computers, since it makes
the old equipment and related knowledge useless and unattractive. The
necessity of the hour is for e-waste to be recycled, collected, or taken
back. Keywords: E-waste, Environment Protection, Waste Management,

Abstract The
present investigation was undertaken to evaluate the physico-chemical
properties of treated tannery effluent discharged from outlet of common
effluent treatment plant (CETP), of industrial area, Unnao district, U.P. and
its impact on Phaseolus aureus Roxb plant. The
tannery waste water were collected for 15
consecutive days. Waste water was analysed for physico-chemical parameters of pollution (temperature, colour, odour, pH, electrical
conductivity, total solids, total dissolved solids, total suspended solids,
hardness, calcium, chloride, alkalinity, B.O.D and C.O.D) and concentration
of some potentially toxic heavy metals (Ni and Cr ). Undiluted and diluted
(25, 50, 75 and 100%) waste water was used to study the growth and
biochemical changes in mung beans (Phaseolus aureus Roxb) seedlings. Distilled water taken as control. The
result revealed that Tannery waste water showed high level of pollution
parameters (total solids 7876mg/l, total dissolved solids 7624 mg/l, total
suspended solids 125 mg/l, hardness 1330mg/l, calcium 1465 mg/l, chloride, 2357
mg/l, alkalinity 535 mg/l, B.O.D 125 mg/l and C.O.D 265 mg/l). Also high concentration of Ni (0.38 mg/l)
and Cr (0.35 mg/l) were analysed. Pollutants in tannery waste water showed
level above the permissible limits of ISI Standards. The waste water was
found unfit for irrigation purposes up to 50% dilution. Undiluted waste water
least inhabited the growth (germination %, root length in cm, shoot length in
cm, fresh weight/plant in gm and dry weight/plant in gm) of green gram
seedling over control. Among biochemical parameters,decreased level of catalase
enzyme and protein content was found in the seedling treated with undiluted
tannery waste water. Seedlings treated at 75% and 100% concentration of waste
water showed highly severity of toxic effects. Use of industrial waste water,
in such form, on agricultural land is not found suitable without proper
treatment. It could be injurious to plants growth and may be a potential
threat to food web. So advance corrective measures to be taken before any
damage. Keywords: Tannery

Abstract The introductive adoptive trial was laid
out during two consecutive autumn seasons of 1989 and 1990 in village Kanharpura of Model Watershed, Rendhar,
Jalaun on farmers fields.
The main objective was expansion of the area of rajmash
cultivation in reclaimed ravines affected soil of Bundelkhand.
Three types farmers holding i.e., Parwa,
mixed Kawar and Kawar
were selected for the experiment. The Parwa
soil produced 21.60 q/ha kernels yield. The mixed
Kawar yielded kernels by 23.00 q/ha. Kawar soil registered the higher productivity of rajmash kernels by 23.80 q/ha, which was higher than the Parwa and mixed Kawar
soils by a margin of 2.20 q/ha and 0.80 q/ha, respectively. The kernels of rajmash obtained from Kawar
soil gave net return of Rs. 2,83,775/ha and BCR
4.87, which were higher over the mixed Kawar
and Parwa soils. The lowest net return of Rs.
2,50,775/ha and BCR 4.42 were recorded from Parwa soil of watershed. Therefore, Kawar soil was found more suitable for cultivation
of rajmash. Keywords: Kawar soil, kernels yield, mixed Kawar soil, Parwa

Abstract In this paper, we
consider the steady flow of two immiscible Newtonian viscous fluids of
different viscosity and density through a rectilinear infinitely long channel
bounded by two plane plates with constant separation having interface in the
mid of the channel. For the channel flow the fluids having (approximately)
same viscosity and density with interface at the centerline the velocity
profile for the fully developed flow is well known. On introducing
considerable difference in viscosity and shifting interface from centerline,
the problem gets complicated because of the mutual effect of the flow
characteristics of the two phases and discontinuity of the viscosity near
interface. An attempt here is made to analyze the flow. Some flow
characteristics e.g. velocity profiles have been evaluated and discussed. The
study and method adopted may be useful for the researchers in geoenvironmental engineering as the study of behavior of
immiscible fluid in soil is very complicated by other methods adopted. Keywords: Flow, Long
channel, velocity, geo-environmental
