Fotosintez [yun. “photos” - yorog’lik va “synthesis” -
birlashish] - yashil o’tlar, suv o’tlari va ayrim mikroorganizmlar 
to’qimalarida 
yorug’lik ta’siri ostida uglekislota va suvdan 
organik moddalarning hosil bo’lishishi va kislorodning ajralib 
chiqishi.
Photosynthesis [greek “photos”-light and “synthesis” - joint, 
combination] -formation in cells of green plants, algae and some 
micro-organisms of organic matters from carbonic acid and water 
under operating of a light accompanied by separation of oxygen. 
Fotosintetik faol radiatsiya (FFR) - o ’simliklaming fotosintez 
jarayonida ishtirok etadigan qoyosh nurlari spkterining 380-710 
mm uzunlikdagi to’lqinlari. FFP energetik birlikda yoki 
kelayotgan umumiy qoyosh radiatsiyasi oqimiga nisbatan % 
hisobida o ’lchanadi.
Photossynthetically active radiation (PAR) - an area of a 
spectrum o f the sun (a wave length o f 380-710 mms), used by 
plantes during photosynthesis. PAR is expressed in power units 
or in % to a general current of a solar radiation.
Xavfli chiqindilar - jamiyat hayot faoliyayida hosil bo’ladigan 
boshqa zararli mahsulot (chiqindilar), notog’ri munosabatda ular 
inson salomatligi yoki atrofga jiddiy zarar yetkazishi mumkin. 
Yonib ketish, tez zanglash, kimyoviy faollik yoki zararlilik kabi 
to’rt xususiyatdan birortasiga ega bo’lgan chiqindilar; 2) 
insonning texnologik faoliyatida natijasida hosil bo’lgan 
chiqindilar, shuningdek, yaroqsiz holga kelgan, hamda inson 
organizmi 
va ekotizimlarga zarar yetkazuvchi kimyoviy

mahsulotlar. X.ch. ulaming surunkali salbiy ta’siri tufayli “sust 
harakatdagi bomba” deyiladi.
Hazardous waste - 1) by products o f society that can pose a 
substantial hazar to ahuman health or the environment when 
improperly managed waste possesses at least one o f four 
characterstics - ignitability, corrosivity, reactivity, or toxicity; 2) 
wasted o f technological activity o f person, and also collapced 
chemical products exercising harm to an organism of a person 
and ecosystems. H.w. are called “time bomb” because o f their 
chronic affecting.
