Asbestos is a hazard pollutant to human health, exposure to asbestos cause serious health effects and wide range of asbestos-related diseases such as asbestosis, lung cancer and malignant mesothelioma and it has been classified as carcinogen by the World Health Organization WHO which cause a carcinogenic effects. Fibers of asbestos are mainly released from friction product in brakes and clutch linings and from reinforce agent in the asbestos cement industry. The aim of this was to evaluate the levels of asbestos fibers in surroundings air of some dense traffic points in Baghdad, through winter 2020. Materials and Methods: Samples of airs was carried out by directing air flow to a mixed cellulose ester membrane filter mounted on an open faced filter holder using a low flow sampling pump. The asbestos fibers that present in the samples were analyzed and counted by using scanning electron microscopy SEM to identify non asbestos from asbestos fibers, SEM coupled to an energy dispersive X-ray EDS analysis method to know the chemical composition of these fibers. Through monitoring of asbestos fiber concentration indicated that a range from 0.097-0.142 f/ml and the average concentration of asbestos fibers in the studied points were 0.11825 f/ml. This values which is considerably higher than the threshold limit value (TLV) proposed by WHO and American conference of governmental industrial hygienist ACGIH which is 0.0022 and f/ ml 0.1 f/ml respectively.
Twenty four samples of various granites and marble used common as flooring materials were collected from many factories and market in Baghdad Province, Iraq. Natural radioactivity of 226Ra, 232Th and 40K in the samples was measured by using high purity germanium detectors with an efficiency of 40%. The Specific activity concentration in granite samples ranged from 9.20 to 79.64 Bq/kg, 10.50 to 229.40 Bq/kg and 185.30 to 1391.20 Bq/kg for 226Ra, 232Th and 40K, respectively. The estimated of radiological parameters: radium equivalent activity (Req), activity concentration Index (I) and hazard indices (internal (Hin) and External (H

Journalists noticed the spread of unprincipled journalists with no journalistic ethics amongst them, they tried to protect their profession from these corrupt outsiders who might annihilate the mighty of journalism. The principles of the journalism profession known as journalistic ethics, are one the most important formulations of the law concluded by the journalists and those concerned by the the profession, they were then published in public in order to prove their professionalism, especially for those who don’t und

Four species were identified including P. longiseta, P. aequiseta, P. proboscidea and P. foreli, with percentags of 51.7 , 36.4, 1.1, and 10.5 % respectively. The first two species found in all sites , while , P. proboscidea found only in S1 and P. foreli only in S2.
This study includedepidermal appendages characters of ten species belongingto the familyAsteraceae.Most of the studied species are characterized by eglandular, glandular, trichomesand papillae which are variable according to itskind, number of cells, shape, dimensions, characteristicsof surrounding cells, wall thickness and the position. Results showed that all species included glandular and eglandulartrichomes exceptCosmos bipinnatus, Ecliptaprostrate, andEupatoriumcannabinum that lacked in glandular trichomes and were based on their specific details.Trichomes were divided into different groups. The glandular ones involved sessile glandular or group multicellular and the head wasmace-shaped or round

The tea plant is known scientifically as Camellia sinensis, when planting and during growth needs to fertilizers, which contents remarkable amounts of Uranium. So it became important to study the concentrations of uranium found in tea. Eight samples of tea had been taking, which represent the most important species used in the Iraqi kitchen, and the Uranium concentrations were measured. The results showed that the average concentration of uranium for all samples were1.005 mg/L, while the average of the annual effective dose was 0.221 mSν/y. The results also indicated that green tea possesses small concentration of Uranium compared with
