Masalah pencemaran udara merupakan persoalan tahunan yang terus terjadi di setiap kota. Kota Surabaya adalah salah satu kota dengan jumlah penduduk yang cukup padat sehingga berbanding lurus dengan jumlah kendaraan bermotor yang digunakan. Kendaraan bermotor serta kawasan perindustrian yang berada di Surabaya menyumbang emisi terbesar ke udara sehingga memiliki kualitas udara yang rendah kareana adanya pencemaran tersebut. Kualitas udara berkaitan erat dengan pencemaran, untuk mengetahui tingkat kadar pencemaran udara pengukuran kualitas udara mengacu pada indeks standar parameter pencemaran udara (ISPU). Parameter pemantauan yang digunakan salah satunya adalah Particulate matter 10. PM10 merupakan pencemar primer yang beremisi langsung ke udara yang berdampak serius bagi kesehatan dan lingkungan. Penelitian ini dilakukan di kawasan Bundaran Taman Pelangi Surabaya selama 3 hari dengan selang waktu hari kerja dan hari libur dengan interval waktu pada pagi, siang dan sore hari. Analisis data konsentrasi dihitung menggunakan alat HVAS dengan metode gravimetri serta dipetakan mengunakan program ArcGIS. Hasil studi menunjukkan konsnetrasi tertinggi pada titik lokasi sampling 6 dengan nilai PM10 = 110.71 μg/m3 , dan terendah pada titik lokasi sampling 1  Pm10= 50.15 μg/m3

SummaryIt has been suggested that human platelets possess the ability to phagocytose particulate matter similar to the polymorphonuclear leukocyte. However some difference of opinion has arisen regarding this contention, particularly as differences have been demonstrated with regard to the observed metabolic changes occurring in platelets related to such a process.The experiments reported in this paper were designed to observe the aerobic and anaerobic metabolism in human platelets during and following interiorization of two different particles, viz. polystyrene latex and thorotrast. The results of these experiments show a marked difference between both types of particles with regard to observable metabolic changes despite the rapid interiorization of both types of material. Some alteration occurs in both aerobic and anaerobic metabolism a considerable time after interiorization of latex, whereas no alteration could be demonstrated after interiorization of thorotrast. It is suggested that the interiorization of particulate matter is by some process other than phagocytosis and that observed metabolic changes related to latex may be due to a release reaction.

Summary1. Infusions containing particulate matter, viz. whole amniotic fluid, amniotic fluid sediment, and glass beads, produce in dogs changes in both early and late phases of the clotting reaction. These changes are associated with the development of pulmonary hypertension.2. When dogs were given an active fibrinolysin followed by an infusion of whole amniotic fluid, the alterations in the clotting mechanism were either delayed or did not appear. No pulmonary hypertension developed in these animals.3. We infer that infusions containing particulate matter will produce in dogs both pulmonary hypertension and changes in the clotting mechanism. Although these are independent changes, both are as closely related to the damage to the pulmonary vessels as they are to the biological nature of the infusions.
