Food safety and monitor of the contents of agricultural products are matters of great
importance for consumers, as a result of food awareness, public health and disease
prevention.
The aim of this study is to know the concentrations of some heavy
metals (lead -
cadmium - nickel - chromium), in some fodder plants (Trifolium ssp., Cynodon dactylon.,
Avena sativa L.), and the extent of its secreted in the milk of cows in the area of Banias on
the Syrian coast.
This research aimed to study some chemical characteristics of rainwater in the region
located at the East of Baniyas area the coastal region of Syria . Baniyas area contain
complex of industrial facilities including oil refinery, electrical power g
eneration station
and oil transportation. pH values, concentration of trace metals (Pb, Cu, and Cd) and major
ions (Ca2+, Mg 2⁺, Na⁺, NH₄⁺, K⁺,SO₄2-, NO3⁻, Cl⁻, F⁻) were determined during the period
from October 2012 to May 2013.
Samples were collected from 15 sites differ in distances from the emissions sources.
Most of samples have normal pH value. The pH values decreased while the concentration
of SO₄2-, NO3⁻, and trace metals Pb, Cu, Cd increased significantly by getting closer to
emission source up on 2500m. The changes of the chemical characteristics of rainwater
were significant.
The end of the twentieth century witnessed increasing interest in environmental
issues from governments around the world, accompanied by great interest from researchers
in the subject of environmental management accounting (EMA).Some research on th
e
subject emphasized the importance and benefits gained from the measurement of
environmental costs and the challenges associated with such measurement. However,
research that tried to document the extent of using (EMA) techniques, and the barriers of
such use, are scarce in the management accounting literature.
This research explores the extent of adopting (EMA)techniques in a sample of Syrian
firms, and the barriers of such adoption.
A questionnaire was developed and distributed to (100) firms working in the costal
area of Syria, of which (23) completed questionnaires were returned and interred into SPSS
for statistical analysis. Sample size in the research is affected by the war in Syria that made
most of the companies out of service.
Results of this research showed that (70%) of the participating firms reported
usageof (EMA) techniques.However results of Binomial test showed that this proportion is
insignificant at 5% significance level. It was found also that a significant proportion (83%)
of the firms in the sample measure environmental treatment costs for the internal usage,
while insignificant proportions (61%, and 65% respectively) measure prevention and
environmental management costs, and the value of wasted material purchased. Significant
barriers for not using (EMA) techniques, reported by respondents, include: difficulty of
the monetary measurement of environmental costs, the absence of a unified guide of
environmental cost measurement at the level of industry, and the lack of knowledge by
management on (EMA).
According to the chemical pollution danger in general and its danger on groundwater
wells in agricultural areas particularly the inhabited ones , the scientific study was
implemented to determine the concentrations of some ions in water wells withi
n the area of
Hraesoon; In addition to, monitoring their changing values which indicate the rate of
chemical pollution in the study area due to existing activities.
The search involves a monthly periodic physical and chemical analyzes in the
invested wells in Hraesoon area , Banias city for a whole year. starting from September
2011 till August 2012 by choosing ten invested wells disterbuted in the area.
The study includes the changing of temperature ,pH, electrical conductivity, and the
group of negative ions (nitrate NO3
-, phosphate PO4
3-, sulphates SO4
2-, chloride Cl-) in
addition to positive ions (ammonium NH4 +, Sodium Na +).
The values of the studied ions have demonstrated a clear disparity in each month for
the samples taken from the same wells, due to the agricultural ,human activities and
climatic conditions that prevailed during the sampling dates.
The recorded results show cases of chemical contamination in the water wells
studied not identical the Syrian standard for drinking water (2011-2012) portend a lot of
health and environmental risks, especially that many of those wells are used for drinking
purposes.
Ornamental plants considered one of the modern plantation, which should be
introduced in the future agricultural development plan confirmed by field studies for the
most important ornamental seed plants as a samples for data collections.
Through i
nformation and field data it can be concluded that, most of nursery's of
ornamental plants were in a small size (less than 2.5 hectare) in comparison with some
other propagated plants due to the absence of specialization. We observed a shortage in a
propagated plant materials especially cut-flowers which considered the most important
product.
This research observed also many problems facing the producers leading to high
production cost: preliminary materials, agriculture and propagation materials, expert
workers beside obstacles in exporting and absence in observation and governmental help.
